Multiplying Polynomails

When Multiplying a polynomial you must use distributive properties.
Multiply the numeral coefficient by each other and combine the variables together.
Then you multiply the coefficient and the constant and add the variable to the answer.
Example : (3x)(5x-4). You multiply (3x)(5x) = 15x^2
Then you multiply (3x)(-4) = -12x. 3 and 5 are the coeffients and x is the variable. The constant is -4.

Important Fact :
+ X + = +
+ X - = -
- X + = -
- X - = +
