In this week we learned how to factor Trinomials
For example 16X^2 + 36X + 8
First, multiply 16 * 8 and find the factors of numbers that multiply towards it until you find the factors that add together to create 36.
So 16 * 8 = 128
128 = 4 * 32
4 + 32 = 36
so once you have done this you will end up with 4X and 32X in your empty squares.
and finally, you will end with (4 + 32X) and (4X + 8).
