# Thread: Writing transform. form of a quad. function in the general form?

1. ## Writing transform. form of a quad. function in the general form?

Hi, I'm kinda stuck on this one... can anyone help me?

How would I write the transformational form of a quadratic function:

$\displaystyle (y+3)=(x+5)^2$

as the General Form

$\displaystyle y=ax^2+bx+c$?

it's what to do with (y+3) that has me confused..

Take 3 from both sides to get rid of that 3.

$\displaystyle y = (x+5)^2 - 3$

See spoiler for expanded form

Spoiler:
$\displaystyle y = x^2 + 10x + 22$
