Factor the polynomial x^3-4x^2-7x+10 completely if -2 is a zero.
Answer by Earlsdon(6294) (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.
