# How to Subtract Polynomials

## Original question text:

How do you subtract the polynomials?

(-6r^2+9r+4) - (6r^2+4)## How can Algebrator help you with this problem?

Algebrator can easily solve problems such as the one you posted. It is a great tool in order to rapidly complete Algebra assignments.

An example using your equation is described following the link below.

To add, subtract or multiply more than one polynomial enter each polynomial in a set of parentheses with the appropriate operator separating each term.

You then have to press the "Solve" button several times in order to obtain a step-by-step solution.

The Explain button, provides the mathematical logic involved in the selected step.

Algebrator then organizes this expression into groups of like terms, so we can combine them easier.

Further simplification is not possible.
