negative 3...............................
I don’t know the 8 percent of what you do
(12x^3-4x^2+8x)/(-2x) The greatest common factor of the numerator and denominator is -2x so upon division by GCF of both numerator and denominator you have:
-6x^2+2x-4 and we can now also factor out -2
-2(3x^2-x+2)
If she has finished 20%, she still has 80% to do. So just calculate .8 times 150.
