How to factor this rational function and characteristics?
(x^3+x^2-6x)/(x^2+2x-8)

I can't factor the numerator to find the x intercepts and some other things, which i have to do ALGEBRAICALLY. Also this is what i have so far for the characteristics.

Domain - (-infinity, + infinity) ?
Range - (-infinity, -4) U (-4,2) U (2, +infinity)
Local Max (-6.-9) Local min (-2,-1) no absolute max/mins?
Increasing Intervals (-infinity, -9) (-1, +infinity)
Decreasing Intervals (-9, +infinity) (+infinity, -1)
Y intercept (0,0) and X Intercept (-3,0) < i used my calculator :\
Holes & discontinuities ?
function is odd
rate of change?
end behavior?

Restrictions on the domain: and

After simplification:



Vertical asymptote at x = -4

Point of discontinuity (hole) at x = 2
