Question

7w^2-91w+252
factor the trinomial.
is the answer 7(w-4)(w-9) or 7(w-9)(w-4)

Answer 1

when multiplying, you can switch the order. 2*3 is the same as 3*2

this works, even for letters or complicated expressions
(w-4)*(w-9) = (w-9)*(w-4)

so 7(w-4)(w-9) or 7(w-9)(w-4)
are the same answer.

Answer 2

thank you!
