Answer:
-8p^4+12p^3+4p^4-8p^2+3p^2
=-8p^4+4p^4+12p^3-8p^2+3p^2
=-4p^4+12p^3-5p^2
=p^2(-4p^2+12p-5)
note: If you have to solve for X
there are steps according to formula
(-4)^-3 =
-4^-3 = 
Basically in this situation there is no difference whether parenthesis are used or not.
Lets say its 30 percent: 8oz x .3 = 2.4oz, therefore 8oz - 2.4oz = 5.6oz of fruit.
Lets say its 40 percent: 8oz x .4 = 3.2oz, therefore 8oz - 3.2oz = 4.8oz of fruit.
So it can range from 4.8 ounces to 5.6 ounces of edible fruit.
