Introduction

In mathematics, factoring is a process of expressing an algebraic expression as a product of simpler expressions. In this article, we will explore how to factor the expression g2+14g+40g^2 + 14g + 40 to find the dimensions of a planned school garden. The expression represents the area of the garden in square feet, and we need to find the factors that can be used to determine the dimensions of the garden.

Understanding the Expression

The given expression is a quadratic expression in the form of ax2+bx+cax^2 + bx + c. In this case, a=1a = 1, b=14b = 14, and c=40c = 40. To factor the expression, we need to find two numbers whose product is acac and whose sum is bb. These numbers are called the roots of the quadratic equation.

Factoring the Expression

To factor the expression g2+14g+40g^2 + 14g + 40, we need to find two numbers whose product is 1×40=401 \times 40 = 40 and whose sum is 1414. These numbers are 1010 and 44, since 10×4=4010 \times 4 = 40 and 10+4=1410 + 4 = 14. Therefore, we can write the expression as:

g2+14g+40=(g+10)(g+4)g^2 + 14g + 40 = (g + 10)(g + 4)

This is the factored form of the expression, and it represents the area of the school garden in square feet.

Finding the Dimensions of the Garden

Now that we have factored the expression, we can use the factored form to find the dimensions of the garden. The factored form (g+10)(g+4)(g + 10)(g + 4) represents the area of the garden as the product of two expressions. To find the dimensions of the garden, we need to find the values of gg that satisfy the equation.

Solving for g

To solve for gg, we can set each factor equal to zero and solve for gg. This gives us:

g+10=0g=10g + 10 = 0 \Rightarrow g = -10

g+4=0g=4g + 4 = 0 \Rightarrow g = -4

Therefore, the values of gg that satisfy the equation are g=10g = -10 and g=4g = -4.

Interpreting the Results

The values of gg that we found represent the dimensions of the garden. Since gg represents the area of the garden in square feet, we can interpret the results as follows:

  • If g=10g = -10, then the area of the garden is 10-10 square feet. However, this is not possible, since the area of a garden cannot be negative. Therefore, we can ignore this solution.
  • If g=4g = -4, then the area of the garden is 4-4 square feet. Again, this is not possible, since the area of a garden cannot be negative. Therefore, we can ignore this solution.

However, we can also interpret the results as follows:

  • If g=10g = 10, then the area of the garden is 1010 square feet.
  • If g=4g = 4, then the area of the garden is 44 square feet.

Therefore, the dimensions of the garden are 1010 feet by 44 feet.

Conclusion

In this article, we explored how to factor the expression g2+14g+40g^2 + 14g + 40 to find the dimensions of a planned school garden. We found that the factored form of the expression is (g+10)(g+4)(g + 10)(g + 4), and we used this form to find the values of gg that satisfy the equation. We interpreted the results as the dimensions of the garden, and we found that the dimensions of the garden are 1010 feet by 44 feet.

    Q&A: Factoring the Expression to Find the Dimensions of the School Garden ====================================================================

Introduction

In our previous article, we explored how to factor the expression g2+14g+40g^2 + 14g + 40 to find the dimensions of a planned school garden. We found that the factored form of the expression is (g+10)(g+4)(g + 10)(g + 4), and we used this form to find the values of gg that satisfy the equation. In this article, we will answer some frequently asked questions about factoring the expression and finding the dimensions of the garden.

Q: What is the purpose of factoring the expression?

A: The purpose of factoring the expression is to find the dimensions of the school garden. By factoring the expression, we can find the values of gg that satisfy the equation, which represent the dimensions of the garden.

Q: How do I factor the expression g2+14g+40g^2 + 14g + 40?

A: To factor the expression g2+14g+40g^2 + 14g + 40, you need to find two numbers whose product is 1×40=401 \times 40 = 40 and whose sum is 1414. These numbers are 1010 and 44, since 10×4=4010 \times 4 = 40 and 10+4=1410 + 4 = 14. Therefore, you can write the expression as:

g2+14g+40=(g+10)(g+4)g^2 + 14g + 40 = (g + 10)(g + 4)

Q: What are the values of gg that satisfy the equation?

A: To find the values of gg that satisfy the equation, you need to set each factor equal to zero and solve for gg. This gives you:

g+10=0g=10g + 10 = 0 \Rightarrow g = -10

g+4=0g=4g + 4 = 0 \Rightarrow g = -4

Therefore, the values of gg that satisfy the equation are g=10g = -10 and g=4g = -4.

Q: How do I interpret the results?

A: To interpret the results, you need to consider the values of gg that you found. Since gg represents the area of the garden in square feet, you can interpret the results as follows:

  • If g=10g = -10, then the area of the garden is 10-10 square feet. However, this is not possible, since the area of a garden cannot be negative. Therefore, you can ignore this solution.
  • If g=4g = -4, then the area of the garden is 4-4 square feet. Again, this is not possible, since the area of a garden cannot be negative. Therefore, you can ignore this solution.
  • If g=10g = 10, then the area of the garden is 1010 square feet.
  • If g=4g = 4, then the area of the garden is 44 square feet.

Therefore, the dimensions of the garden are 1010 feet by 44 feet.

Q: What are some common mistakes to avoid when factoring the expression?

A: Some common mistakes to avoid when factoring the expression include:

  • Not finding the correct values of gg that satisfy the equation.
  • Not interpreting the results correctly.
  • Not considering the possibility of negative values of gg.

Q: How can I practice factoring the expression?

A: You can practice factoring the expression by trying different values of gg and seeing if they satisfy the equation. You can also try factoring different expressions and see if you can find the correct values of gg that satisfy the equation.
