# What is the standard form of y= (-9x-7)(2x-7) ?

Nov 22, 2015

To find the standard form, you need to expand the equation.

#### Explanation:

$y = \left(- 9 x - 7\right) \left(2 x - 7\right)$
$- 18 {x}^{2} + 56 x - 14 x + 49$

Then, simplify the equation.

You will get

$- 18 {x}^{2} + 42 x + 49$
