This week we worked on polynomials and I learned how to apply the distributive law when multiplying.
If your equation was 7x(2-3) you would have to distribute the 7x to everything in the brackets, so multiply the 7x by 2 and -3. The expanded form should be 14x-21x. Then you would collect the like terms and the simplified answer would be -7x.
If you were working with two sets of brackets, you would do the same thing, except distribute more than one term.
Don’t forget to add the exponents together when you are multiplying.
Here are some examples:
