That is the difference of two squares. Remember that a^2 - b^2 = (a+b)(a-b)

Think of "a" as 5w and "b" as 12.

Now write down the answer.

25+12=37

25-12=13

37*13=481

so the answer is 481??

No. Where did the w go?

They are asking for the expression

25w^2 - 144

to be factored, not evalauated.

The answer is

(5w + 12)(5w - 12)
