Answer
$$x(x + 5)(x - 5)$$
Work Step by Step
For this expression, we see that we can factor out an $x$ for both terms, so we have:
$$x(x^2 - 25)$$
The binomial in parentheses is the difference of squares, so we can use the following formula to factor the difference of squares:
$$A^2 - B^2 = (A + B)(A - B)$$
In this case, $A$ is the $\sqrt x^2$ or $x$ and $B$ is the $\sqrt 25$ or $5$. Let us plug these values into the formula:
$$x(x + 5)(x - 5)$$
