Question

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

Answer 1

(p-q)(a-1)

Explanation:

Answer 2

(p - q) (a - 1)

Explanation:

To change q - p as p - q we pull out -1So q - p becomes

-1(p - q)a(p–q)+q–p

a(p–q) -1(p - q)

p -q is in common so we factor out

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