Use FOIL:
(2x + 4)(x - 8) = 2x·x + 2x·(−8) + 4·x + 4·(−8)
= 2x^2 − 16x + 4x − 32
= 2x^2 − 12x − 32
You can factor out 2: 2(x^2 − 6x − 16) = 2(x − 8)(x + 2).
(2x + 4)(x - 8) = 2x·x + 2x·(−8) + 4·x + 4·(−8)
= 2x^2 − 16x + 4x − 32
= 2x^2 − 12x − 32
You can factor out 2: 2(x^2 − 6x − 16) = 2(x − 8)(x + 2).
