Adding and Subtracting Polynomials

Apolynomialis a mathematical expression which is consisting of sum of different terms, where each term includes a variable or variables raised to a power and multiplied by a coefficient.  The simplest polynomials have one variable.Some polynomials have two, three, or more variables.  A polynomial in one variable is called a univariate polynomial. A polynomial in two variables is known as a bivariate polynomial.

Tosimplify algebraic expressions,

Step 1:  Simplify within the parentheses, which normally doesn't apply when adding and subtracting polynomials.  

Step 2:  Use distributive property to eliminate the parentheses.

Step 3:  Combine the like terms.

Step 4:  Write in descending order.

For subtraction first rewrite the subtraction as addition, i.e. to change subtraction to addition, add the opposite or additive inverse. Then follow all four steps.
