Answer:

x² - 64

Step-by-step explanation:

Given

(x + 8)(x - 8)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x - 8) + 8(x - 8) ← distribute both parenthesis

= x² - 8x + 8x - 64 ← collect like terms

= x² - 64

erma4kov [3.2K]

Answer:

x=7

Step-by-step explanation:

expand 4(x+5): 4x+20

2x+34=4x+20

subtract 34 from both sides

2x+34-34=4x+20-34

2x=4x-14

subtract 4x from both sides

2x-4x=4x-14-4x

-2x=-14

divide both sides by -2

-2x/-2=-14/-2

x=7
