Question

Have to completely factor this...

144-9p^2

[my factoring]:

(12 - 3p) x (12p + 12p)
9(3 - p) = 12 + p --> (or is it 3 + p) ?

Answer 1

12^2-(3p)^2
a^2-b^2=(a+b)(a-b)
hence 12-3p)(12+3p)
if you want you can further take 3 from both factors.
please like my answer it would be helpful.
thanks
