Question

(p^2 - q^2)/(p+q) times (p-q)/(p+q) does this equal p^2-2pq+q^2?

Answer 1

p^2-q^2 = (p+q)(p-q)
so-> (p^2 - q^2)/(p+q) * (p-q)/(p+q) = (p-q)(p-q)/(p+q)

Answer 2

= (p^2 -2pq +q^2) /(p+q)

Answer 3

so would I need to simplify that into (p-q) as my final answer?

Answer 4

no, it can't be simplified into (p-q)
(p^2 -2pq +q^2) /(p+q) can't be simplifed because there is no common factor between the numerator and denominator

Answer 5

oh ok, thanks
