How do you do the foil method with polynomials?

Step-by-step:

For example,

(x+4)(x-4)(x-3)

group the first two and do foil like normal ignoring the "(x-3)"

You should end up with the answer x^2-16

Now multiply (x^2-16) with (x-3)

that answer should be x^3-3x^2-16x+48

what is the starting amount? the question is not clear sorry.

step-by-step explanation:

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
