Question

How do you add and subtract polynomials

Answer 1

Answer:

You add and subtract polynomials based on what their exponent is.

Step-by-step explanation:

If they have the same exponent and they want you to add or subtract it, add and/or subtract it like normal numbers.

Answer 2

Answer:

Your first step is to change the subtraction problem to an addition problem. Then you add, just as you did in the adding polynomials lesson. Let's take a look at an example. Once we change this problem to an addition problem, we will use the horizontal method for solving.

Step-by-step explanation:

You add polynomials when there are plus signs. You subtract them when there is a minus sign. Remember to only add/subtract like terms within the polynomials.
