Question

solve the polynomial equation hhhhheeeeellllpppppppppp!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

x^3-3x+2=0
6x^3-11x^2+6x-1=0
(2x+1)(3x-2)^3(2x-7)=0
2x^3+5x^2-200x-500=0
x^4-x^3-11x^2=x+12

Answer 1

You know, this is too much for one question. But let's tackle the first one.

Answer 2

The possible rational roots of the first equation are +-1, +-2.
Let's use synthetic division to see if any of these possible roots are actually roots.
