Simplify the expression below

OpenStudy (danielbarriosr1):

\[3x(x-11)+8-3x ^{2}\]

OpenStudy (mathstudent55):

First, multiply out the 3x using the distributive property. a(b - c) = ab - ac

OpenStudy (danielbarriosr1):

and then?

OpenStudy (mathstudent55):

Then you need to combine like terms. Like terms are terms that have the same variable part. That means the same variables and exponents.

OpenStudy (danielbarriosr1):

and what about the \[3x ^{2}\]

OpenStudy (mathstudent55):

The first thing you should do is multiply out the 3x and copy everything else. The first line you should get is \(3x^2 - 33x + 8 - 3x^2\) Did you get this after distributing the 3x?
