# Completing the Square and Square Root Property

Not what you're looking for?

Use the square root property to solve the following equations.

x^2= 169

x^2-12=0

5x^2-65=0

(x-2)^2= 25

Solve the equation by completing the square.

x^2+4x-21=0

x^2+16x+43=0

x^2+12x=-13

x^2+15=-10x

4x^2+16x+7=0

Use the quadratic formula to solve the following equations

x^2+7x+6=0

x^2-22x+121=0

2x^2-(square root 7)x-1=0

x^2+16x+53=0

2x^2+12x=-5

4x^2=-12x-3
