In algebra, factoring is a process of expressing an algebraic expression as a product of simpler expressions. A completely factored expression is one that cannot be further simplified by factoring. In this article, we will examine four algebraic expressions and determine which ones are completely factored.

What is Factoring?

Factoring is a fundamental concept in algebra that involves expressing an algebraic expression as a product of simpler expressions. It is a process of breaking down a complex expression into simpler components that can be multiplied together to obtain the original expression. Factoring is an essential tool in algebra, as it allows us to simplify complex expressions, solve equations, and analyze functions.

How to Factor Algebraic Expressions

There are several techniques for factoring algebraic expressions, including:

  • Greatest Common Factor (GCF): This involves finding the largest factor that divides each term in the expression.
  • Difference of Squares: This involves factoring expressions of the form a2b2a^2 - b^2.
  • Sum and Difference: This involves factoring expressions of the form a2+b2a^2 + b^2 and a2b2a^2 - b^2.
  • Grouping: This involves factoring expressions by grouping terms together.

Examining the Expressions

Let's examine each of the four expressions and determine which ones are completely factored.

A. 24x618x5=6x5(4x3)24x^6 - 18x^5 = 6x^5(4x - 3)

To determine if this expression is completely factored, we need to check if it can be further simplified by factoring. The expression 6x5(4x3)6x^5(4x - 3) is already factored, as it is a product of two simpler expressions. However, we can further simplify the expression by factoring out a common factor of 6x56x^5. This gives us:

24x618x5=6x5(4x3)24x^6 - 18x^5 = 6x^5(4x - 3)

This expression is not completely factored, as it can be further simplified by factoring out a common factor of 6x56x^5.

B. 12x5+8x3=2x3(6x2+4)12x^5 + 8x^3 = 2x^3(6x^2 + 4)

To determine if this expression is completely factored, we need to check if it can be further simplified by factoring. The expression 2x3(6x2+4)2x^3(6x^2 + 4) is already factored, as it is a product of two simpler expressions. However, we can further simplify the expression by factoring out a common factor of 2x32x^3. This gives us:

12x5+8x3=2x3(6x2+4)12x^5 + 8x^3 = 2x^3(6x^2 + 4)

This expression is not completely factored, as it can be further simplified by factoring out a common factor of 2x32x^3.

C. 20x3+12x2=4x2(5x+3)20x^3 + 12x^2 = 4x^2(5x + 3)

To determine if this expression is completely factored, we need to check if it can be further simplified by factoring. The expression 4x2(5x+3)4x^2(5x + 3) is already factored, as it is a product of two simpler expressions. However, we can further simplify the expression by factoring out a common factor of 4x24x^2. This gives us:

20x3+12x2=4x2(5x+3)20x^3 + 12x^2 = 4x^2(5x + 3)

This expression is not completely factored, as it can be further simplified by factoring out a common factor of 4x24x^2.

D. 18x412x2=6x2(3x22)18x^4 - 12x^2 = 6x^2(3x^2 - 2)

To determine if this expression is completely factored, we need to check if it can be further simplified by factoring. The expression 6x2(3x22)6x^2(3x^2 - 2) is already factored, as it is a product of two simpler expressions. However, we can further simplify the expression by factoring out a common factor of 6x26x^2. This gives us:

18x412x2=6x2(3x22)18x^4 - 12x^2 = 6x^2(3x^2 - 2)

This expression is not completely factored, as it can be further simplified by factoring out a common factor of 6x26x^2.

Conclusion

In conclusion, none of the four expressions are completely factored. Each expression can be further simplified by factoring out a common factor. Factoring is an essential tool in algebra, as it allows us to simplify complex expressions, solve equations, and analyze functions.
