I need to know how to complete the square.. every website I go to about this is completely complicated.. my math teacher does it like so:(adsbygoogle = window.adsbygoogle || []).push({});

y = x^2 + 6x -7

y = x^2 + 6x + 3^2 - 9 - 7

y = (x + 3)^2 - 16

that I understand but..

if it were to say y = 2x^2 + 6x - 7

that's where I get confused because of the 2 infront of the x^2

I appreciate any help... -scaez
