Example 2 - equations with fractions with the same denominator did you notice how multiplying by 2 (the denominator of both fractions) allowed us to get rid of the fractions this is the best way to deal with equations that contain fractions. In the language of algebra, the distributive property looks like this: a(b + c) = a(b) + a(c), where a, b, and c are terms, either just numbers or numbers with variables, and the parentheses mean. Recall that multiplication is implied when there is no sign between a variable or set of parentheses and a number, another variable, or another set of parentheses therefore in this problem, the x 3 and y 4 are being multiplied. If you remembered that two variables next to each other are multiplied, you might guess that you would multiply two sets of parentheses side by side too so (3)(5) is equal to 3 ⋅ 5 , which is equal to 15.
How to multiply polynomials polynomials are mathematical structures with strands of terms made up of numerical constants and variables there are certain ways that polynomials must be multiplied based on how many terms are contained.

Multi-step linear equations to move a term with the variable 4 multiply or divide to isolate the variable to remove parentheses or multiplying both sides. This prealgebra-arithmetic lesson explains how to do the order of operations with parenthesis.
Remember you can only multiply variables with exponents with the same variables with exponents you cannot multiply, for example, n² with x³ since n and x are different exponents distributing products when multiplying paranthesis. 4) simplify further by multiplying or dividing the leftover expressions let's go over six (6) examples with varying levels of difficulty examples of simplifying factorials with variables.
