Pls, I need help in this one. it's that urgent Factor the polynomial x^3-4x^2-7x+10 completely if -2 is a zero.Answer by Earlsdon(6287)   (Show Source): You can put this solution on YOUR website!Factor: if -2 is a "zero" If -2 is a zero of this equation, then x+2 is one of the factors of the equation. To find the other two factors, you should divide the given equation by x+2. When I did this, I got: Now you can factor this into: so the complete factorisation of the given equation would be: You can confirm this by multiplying these three factors to see that you get back the given equation.
