25w^2-144

• Math -

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.

• Math -

25+12=37
25-12=13
37*13=481

• Math -

No. Where did the w go?
They are asking for the expression
25w^2 - 144
to be factored, not evalauated.

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