Normally, such equations are solved via „guessing“ one root, in this case x=3, and then do a simple polynomial division - this is sooooo much faster than the two methods shown here…

👍👍👍
x^3-x^2+2x-24=0 , (x-3)(x^2+2x+8)=0 , x^2+2x+8=0 , x=(-2+/-V(4-32))/2 , x=(-2+/-i*V(28))/2 , x=-1+/-i*V7 , 1 -3 solu , x= 3 , -1+i*V7 , -1-i*V7 , 2 -6 8 -24
So you solve this equation and you are admitted to Stanford? Come on, be serious...
