Michelle is a baker. to make 6 pies she uses
7 1/2 cups of flour. how many cups of flour is needed to make 1 pie?

If she uses 7.5 cups of flowers for 6 pies, then you need to find the "ratio". So first you need to divide 6 from 7.5, and that gets you 1.25. So that means that for one pie she uses 1.25 cups of flour!

step-by-step explanation:

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
