MULTIPLYING POLYNOMIALS
SIMPLE
Multiplying polynomials is easy especially when facing with simple polynomials such as in the example on right. A polynomial "K-6" is the expression with two terms, "6" is represented as a constant and "k" is is represented as a variable. When they ask you to "Expand and simplfy" you just have to us "FOIL METHOD", which states that take one term at a time from first polynomial and mupltiply it with every term in the second polynomial and so on. Than collect the like terms to simplify, as done in the example on the right.
Mediocore
This expression is completely the same as the simple expression from above but you have two choices you can do to solve this expression. The first is multiplying the "-3" with the first bracket of polynomials and evaluate the same way as you did on the simple expression (Above). Or you can leave the three out and evaluate your polynomials as above and at the end, you multiply everything by "-3" to finish the evaluation.
COMPLEX
This expression is combined with three smaller expressions with the first having multiple of "2x". First, you multiply "2x" with "(3x-4). when you have your answer you begin by adding your first two expressions together (vice versa if it is with a negative but you switch the signs from the subtraction sign to the second expression that comes after). when you get your answer, you finally subtract with your third expression by switching all the signs starting from the subtrction sign all the way to the third expression. Group like terms and evaluate to recieve your answer.
