# What is the standard form of y= (6x + 3)(x - 5) ?

Mar 25, 2018

$y = 6 {x}^{2} - 27 x - 15$

#### Explanation:

Standard form means that you need to expand the expression and list each term as decreasing powers of $x$:

$y = \left(6 x + 3\right) \left(x - 5\right)$

$y = 6 {x}^{2} - 30 x + 3 x - 15$

$y = 6 {x}^{2} - 27 x - 15$
