Question 41052: I need to understand a detailed explanation involved and I need to solve each equation by the square root method. Show each step involved in finding the solutions. Put all solutions in simplest form.
a: x^2 - 13 = 0
b: 16x^2 = 9
c: (x - 5)^2 = 27

You can put this solution on YOUR website!
a: x^2 - 13 = 0
x^2 = 13 add thirteen
x = sqrt%2813%29 or -sqrt%2813%29 square root each side
b: 16x^2 = 9
x^2 = 9/16 divide each side by sixteen
x = 3/4 or -3/4 square root each side
c: (x - 5)^2 = 27
x - 5 = +-sqrt%2827%29 square root each side
x = 5 +-sqrt%2827%29 add five
