Question 440890: Can this be factored or is the problem wrong?
x^3+8x^2-11x-12
I have tried all possible factors for 12 eg...1,2,3,4,6 and 12 both negative and positive values. When I substitute back in the eqn to find the first factor I do not get any zeros, hence not able to find the first factor before I start dividing.

not sure about wrong...but the graph shows NO integer factors
