How do I solve a quadratic equation x^2  x = 30 by completing the square
I don't understandcould someone just explain the steps to solving this

I found this example on purplemath
You coul use this and apply knowledge.
This is the original equation. x2 + 6x – 7 = 0
Move the loose number over to the other side. x2 + 6x = 7
Take half of the xterm (that is, divide it by two) (and don't forget the sign!), and square it. Add this square to both sides of the equation.
Convert the lefthand side to squared form. Simplify the righthand side. (x + 3)2 = 16
Squareroot both sides. Remember to do "±" on the righthand side. x + 3 = ± 4
Solve for "x =". Remember that the "±" gives you two solutions. Simplify as necessary. x = – 3 ± 4
= – 3 – 4, –3 + 4
= –7, +1 
Thank you

you're welcome!
