Q10 plz I need the answer asap

Answer 1

(6P-4M)(6P+4M)

Explanation:

`36P^2-16M^2` can be factored using the "difference of squares" formula which is
`a^(2)-b^(2)=(a+b)(a-b)`.

6*6=36 and 4*4=16; P*P=P^2 and M*M=M^2 -- from this we know that the two variables on each side of the minus sign are perfect squares. Now, see
`36P^2-16M^2` as
`(6P)^2-(4M)^2` to make it fit nicer to the formula.

So,
`(6P)^2-(4M)^2=(6P+4M)(6P-4M)`.

If you forget the formula, you can always go backward on multiple-choice questions like this one. Use FOIL to expand your factored answers.
