Simplify the following expression.
(4x-8)(4x+8)
a. 16x2 + 64x - 64
ob. 16x2 - 64
oc. 167²-16
od. 16x² - 644-64

Step-by-step explanation:

(4x - 8)(4x + 8)

using the FOIL methodfirst, outside, inside, last

First : multiply first terms in each set4x * 4x = 16x^2

Outside : multiply outside terms4x * 8 = 32x

Inside : multiply inside terms...-8 * 4x = -32x

Last : multiply last terms-8 * 8 = -64

now we have :

16x^2 + 32x - 32x  -64...notice how ur x terms cancel out

16x^2 - 64 <==
