Introduction

When it comes to factoring quadratic trinomials, understanding the relationship between the coefficients is crucial. A quadratic trinomial of the form $x^2 + bx + c$ can be factored as $(x + p)(x + q)$. In this article, we will explore the relationship between the coefficients $b$ and $c$ and the values of $p$ and $q$.

The Relationship Between Coefficients

To factor a quadratic trinomial, we need to find two numbers $p$ and $q$ such that their sum is equal to the coefficient of the linear term ($b$) and their product is equal to the constant term ($c$). This can be represented as:

$$x^2 + bx + c = (x + p)(x + q)$$

Expanding the right-hand side of the equation, we get:

$$x^2 + bx + c = x^2 + (p + q)x + pq$$

Comparing the coefficients of the two sides of the equation, we can see that:

• The coefficient of the linear term ($b$) is equal to the sum of $p$ and $q$.
• The constant term ($c$) is equal to the product of $p$ and $q$.

Selecting the Correct Statements

Based on the relationship between the coefficients and the values of $p$ and $q$, we can select the two true statements about $b$ and $c$.

• A. $b = p + q$: This statement is true, as the coefficient of the linear term ($b$) is equal to the sum of $p$ and $q$.
• C. $c = p + q$: This statement is also true, as the constant term ($c$) is equal to the product of $p$ and $q$.

The other options are incorrect because:

• B. $b = p - q$: This statement is incorrect, as the coefficient of the linear term ($b$) is equal to the sum of $p$ and $q$, not the difference.
• D. $c = p - q$: This statement is also incorrect, as the constant term ($c$) is equal to the product of $p$ and $q$, not the difference.

Conclusion

In conclusion, when factoring quadratic trinomials, it is essential to understand the relationship between the coefficients and the values of $p$ and $q$. By comparing the coefficients of the two sides of the equation, we can determine the correct statements about $b$ and $c$. Remember, the coefficient of the linear term ($b$) is equal to the sum of $p$ and $q$, and the constant term ($c$) is equal to the product of $p$ and $q$.

Examples and Practice

To reinforce your understanding of the relationship between the coefficients and the values of $p$ and $q$, try factoring the following quadratic trinomials:

• $x^2 + 5x + 6$
• $x^2 - 3x - 4$
• $x^2 + 2x - 15$

Use the relationship between the coefficients and the values of $p$ and $q$ to determine the correct factors for each quadratic trinomial.

Tips and Tricks

When factoring quadratic trinomials, remember to:

• Use the relationship between the coefficients and the values of $p$ and $q$ to determine the correct factors.
• Compare the coefficients of the two sides of the equation to ensure that they are equal.
• Use the product of $p$ and $q$ to determine the constant term ($c$).
• Use the sum of $p$ and $q$ to determine the coefficient of the linear term ($b$).

By following these tips and tricks, you will be able to factor quadratic trinomials with ease and confidence.

Common Mistakes to Avoid

When factoring quadratic trinomials, be careful not to make the following common mistakes:

• Mistake 1: Assuming that the coefficient of the linear term ($b$) is equal to the difference of $p$ and $q$.
• Mistake 2: Assuming that the constant term ($c$) is equal to the difference of $p$ and $q$.
• Mistake 3: Failing to compare the coefficients of the two sides of the equation.

By avoiding these common mistakes, you will be able to factor quadratic trinomials accurately and efficiently.

Conclusion

In conclusion, factoring quadratic trinomials requires a deep understanding of the relationship between the coefficients and the values of $p$ and $q$.
