Rewrite the equation by completing the square x^2+12x-13=0

Step-by-step explanation:

In order to complete the square, you want to convert a quadratic from the form -

to the form-

If you're in a hurry,

and you can convert from there.

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
