From first to last, order the steps to prove that expression A is equivalent to expression B.

Question

Expression A: (x+4)(x−2)

Expression B: x2+2x−8

Answer 1

1. Simplify the expression A by distributive property:

(x + 4)(x - 2)
= x(x - 2) + 4(x - 2)
= x^2 - 2x + 4x - 8
= x^2 + 2x - 8

2. Express the simplified form of expression A as expression B:

Therefore, expression A: (x + 4)(x - 2) is equivalent to expression B: x^2 + 2x - 8.
