    finding X intercepts

    u probalbly dnt use this but i just had to post this for pple like me wanting to know the anwer it is 3 unit stuff but x^3 + x^2 - 5x - 6=0 factors of -6 where x^3 + x^2 - 5x - 6=0 when x = -2 -8 +4 + 10 - 6 =0 therefore (x+2) is a factor remember (x-a) into P(a)=0 divided x+2 into x^3 + x^2...
