Question

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

Answer 1

Answer:

$(x+6)^{2}-49$

Step-by-step explanation:

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

$ax^{2}+bx+c$

to the form-

$a(x+d)^{2}+e=0$

If you're in a hurry,

$d=\frac{b}{2a}\\e=c-\frac{b^{2}}{4a}$

and you can convert from there.
