factorising quadratics

[jennymac]

I will put that a little clearer


x cubed minus 2x cubed minus 11x minus 12

Thank you in anticipation

er...
do you mean

x^3 - 2x^3 - 11x -12 or
x^3 - 2x� - 11x -12?

=0?

anyway, neither are quadratics, they are cubic equations.

[ugly_bob]

for x^3 - 2x� - 11x -12, there is only one real factor, (x-4.8)

Thanks for your time to answer I will go through your answers and see if I can make sense of it.
