Question

Solve (7x + 2)2 = 64

Answer 1

first, distribute the 2 to the numbers inside the parentheses:

you'll get: 14x + 4 = 64

subtract 4 from  both sides to get the x value by itself.

you'll get: 14x = 60

divide both sides by 14 to get the x value

you'll get: x = 60/14 or x = 4.29

Answer 2

(7x+2)2=64
14x+4=64
14x=60
x=$\frac{60}{14}$=$\frac{30}{7}$
