Solve (7x + 2)2 = 64
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
(7x+2)2=6414x+4=6414x=60x=\(\frac{60}{14}\)=\(\frac{30}{7}\)
