# What is the standard form of  y= (5x+2)^2 + 11(5x+2)+30 ?

May 6, 2016

Standard form of a quadratic is $a {x}^{2} + b x + c$

#### Explanation:

This expression can be considered as being in standard form already, if you let $\left(5 x + 2\right) = m$

It then becomes $y = {m}^{2} + 11 m + 30$

However, if you multiply out and simplify it becomes:

$y = 25 {x}^{2} + 75 x + 56$
