i'm not quite sure how to factor these..
Factor out the GCF (m-9)(m+1)+(m-9)(m+2) ^^I know i should use the grouping method.. so would it be (m+1)+(m+2)(m-9)?? orrrrr do i need an pair of brackets? [(m+1)+(m+2)](m-9) ?? m^5(r+s)+m^5(t+u) ^^grouping in that one too.. but i sorta have an idea but it may be wrong.. answer may be (m^5)(r+s)(t+u) ?? Factoring polynomials (a+b)^2-(a-b)^2 that's alll.. any help would be greatlyy appreciated. thank you.

for factoring the GCF, the answer would be the second one because the common factor is (m-9).
for factoring polynomials, what are you asked to do? simplify? because that's already in factored form. |
