anonymous · Answer

(x-6)(x+1)(x+4)=x^3-x^2-26x-24

anonymous · Answer

In order for those numbers, -6, 1 and 4 to be roots the function must equal to zero when x=-6, x=1 and x=4. Plugging in is faster than factoring, the answer is x^3+x^2-26x+24

anonymous · Answer

which one is correct??

anonymous · Answer

damoss is correct, i should have written (x+6)(x-1)(x-4)=x^3+x^2-26 x+24

anonymous · Answer

you need to flip the sign of the numbers first before factoring them
