Math tutoring on Adding and Subtracting Polynomials

A Polynomial is a mathematical expression which is consisting of the 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.

To simplify algebraic expressions, following steps are followed in math tutoring:

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

·       Step 2:  Use the 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, then add the opposite or additive inverse. Then follow all four steps.
