# What is the vertex form of y=x^2-22x-3?

Apr 24, 2018

$y = {\left(x - 11\right)}^{2} - 124$

#### Explanation:

You complete the square.

You get
$y = \left({x}^{2} - 22 x + {11}^{2}\right) - {11}^{2} - 3$

You get that ${11}^{2}$ is 121. You simplify, and you get
$y = {\left(x - 11\right)}^{2} - 124$
