# What is the standard form of  y= -9(x-1)(2x-4)(3x-1)?

Feb 13, 2016

the standard form of expression is $y = a {x}^{3} + b {x}^{2} + c x + d$

#### Explanation:

As the highest power in the algebraic expression

−9(x−1)(2x−4)(3x−1) is ${x}^{3}$, the standard form of this is

$y = a {x}^{3} + b {x}^{2} + c x + d$

Actual expansion of te expression gives us

$y = - 54 {x}^{3} + 180 {x}^{2} - 162 x + 36$
