Answer
$x$($x^{2}$ - 4)
= $x$($x$ + 2)($x$ - 2)
Work Step by Step
To factor this polynomial, start by looking for the greatest common factor between both terms. Since the GCF has already been found for the first term, we must apply the formula A^2 - B^2 = (A + B)(A - B) to the second term. The result will create three different terms and is the final answer.
