This week in math we got to learn how to foil polynomials. If you have to multiply two binomials you can use foil to solve the equation. Once you are done foiling you have to group the like terms together.
Example:
(9+7x)(2x+4)+(5+x)(3x+1)
=
=
=
After you’re done grouping the like terms together, the equation is fully simplified.
