$\left(x+2\right)^2\left(x-2\right)$
Learn how to solve problems step by step online. Solve the product (x+2)(x-2)(x+2). When multiplying two powers that have the same base (x+2), you can add the exponents. A binomial squared (sum) is equal to the square of the first term, plus the double product of the first by the second, plus the square of the second term. In other words: (a+b)^2=a^2+2ab+b^2. We can multiply the polynomials \left(x^2+4x+4\right)\left(x-2\right) by using the FOIL method. The acronym F O I L stands for multiplying the terms in each bracket in the following order: First by First (F\times F), Outer by Outer (O\times O), Inner by Inner (I\times I), Last by Last (L\times L). Then, combine the four terms in a sum.
