What is polynomial expressions?

A polynomial is known to be a type of  an expression that is made up of variables, constants and exponents. They are often combined using the mathematical terms such as addition, subtraction, etc.

2 q² - q - 8) - (2 q² + q - 4)

= (2 q² - q - 8) + (-2 q² - q + 4)

Then you have to rewrite subtraction as addition and then Group like terms together;

= (2 q² - 2 q²) + (-q - q) + (-8 + 4)

= -2q - 4
