Factorise ab + b^2 − ac – bc.
a. (b − c)(a − c) b. (b + a)(b + c) c. (b − c)(a + b) d. (b + c)(a - b)
(b + a)(b + c)
(b − c)(a + b)
(b − c)(a − c)
(b + c)(a - b)

I assume you're missing an exponent on the b. As is, none of the answers is correct. The "correct" answer works if it's a b^2 instead of b for the second term.
