Factoring a Sum and Difference of Cubes: Kuta Software Answers

Every now and then, a topic captures people’s attention in unexpected ways. Factoring sums and differences of cubes is one such topic that often challenges students and educators alike. Whether you're tackling algebra homework or preparing for exams, understanding how to factor these expressions correctly is essential.

Introduction to Sum and Difference of Cubes

Factoring a sum or difference of cubes involves specific formulas that simplify expressions like \(a^3 + b^3\) and \(a^3 - b^3\). These formulas break down complex cubic expressions into products of polynomials, making them easier to solve or analyze.

The sum of cubes formula is:

\[ a^3 + b^3 = (a + b)(a^2 - ab + b^2) \]

The difference of cubes formula is:

\[ a^3 - b^3 = (a - b)(a^2 + ab + b^2) \]

Recognizing these patterns is key to successfully factoring cubic expressions.

Step-by-Step Factoring with Kuta Software Answers

Consider the expression \(8x^3 + 27\). Using the sum of cubes formula, we identify:

• \(a = 2x\) because \((2x)^3 = 8x^3\)
• \(b = 3\) because \(3^3 = 27\)

Therefore:

\[8x^3 + 27 = (2x + 3)((2x)^2 - (2x)(3) + 3^2) = (2x + 3)(4x^2 - 6x + 9)\]
