# Week 8 math 10

This week in math we learnt how to simplify and expand polynomials.

First if you were looking to simplify a polynomial you would need to eliminate the brackets then group like terms together. After you’ve done so depending on weather or not the sing in front if the number is a positive or negative you will to either add or subtract the number from the like terms.

Secondly if you were looking to expaned a polynomial you would need to distribut through out it. To do this you must take the nuber out I front of the brackets and multiply it by each number inside the brackets.
