How do you solve quadratic equations using the square root property?

Question

What steps do you take when trying to solve a quadratic equation using the square root property?

Answer 1

First, complete the square.  This will get your quadratic equation into the form

a(x-r)^2 = s, which means (x-r)^2 = s/a.

Hit that with a square root, to get x-r = +- sqrt(s/a).  Add r, and you're done.
