Question

question 5 of 10
the following polynomial can be factored using the techniques of this lesson.
$x^{2}-36$
a. true
b. false

Explanation:

Step1: Recognize difference - of - squares

The expression $x^{2}-36$ is in the form $a^{2}-b^{2}$, where $a = x$ and $b = 6$.

Step2: Apply difference - of - squares formula

The difference - of - squares formula is $a^{2}-b^{2}=(a + b)(a - b)$. So $x^{2}-36=(x + 6)(x - 6)$.

Answer:

A. True
