Can someone help me solve the following equation?
$ 3z^3 + 2z^2 = 6z-4 $
Can someone help me solve the following equation?
$ 3z^3 + 2z^2 = 6z-4 $
If $P(z)=3z^3+2z^2-6z+4$, then $P(-2)=0$ so you can factorize $P$; thus, you only have to solve an equation of degree two.
Your equation has $z=-2$ as one of its roots. You should be able to take it from there.
