Question

Write the expression as a product of polynomials:
a(p–q)+q–p

Answer 1

(p-q)(a-1)

Is this for rsm? I go there too! This one was pretty hard, i hope i helped!

Answer 2

(p-q)(a-1)

Explanation:

a(p–q)+q–p

we can write this expression as

a(p-q)+(q-p)

from second parenthesis we can factor out -1 , so we get

a(p-q) -1(p-q)

Now it has two terms a(p-q) and -1(p-q) , from these two terms we can factor out (p-q)

So we get it

(p-q)(a-1)
