How to solve a third degree equation
Webx 3 −8 = x 3 −2 3. And so we can turn it into this: x 3 −8 = (x−2) (x 2 +2x+4) There is a root at x=2, because: (2−2) (22+2×2+4) = (0)(22+2×2+4) And we can then solve the quadratic … WebOne way to see what's going on here is to rewrite the equation with all the i 's on one side: z 3 + 2 z 2 + 5 z = i ( z 2 + 2 z + 5) Factoring the left hand side as z ( z 2 + 2 z + 5), it's clear you can move things back to get ( z − i) ( z 2 + 2 z + 5) = 0
