It is x = -5

IMPOSSIBLE

No.

x3 + 2x2 - 8x + 5 = 0 x(2x - 8) + 5 = 0

If: x3+1 = 65 Then: x3 = 65-1 And: x3 = 64 So: x = 4 by means of the cube root function on the calculator

No.

y2=x3+3x2

No, it is not.

(xn+2-1)/(x2-1)

X3 - 4 = 2 X3 = 6 X = 61/3 X = about 1.817

x3 + 2x2 - 8x + 5 = 0 x(2x - 8) + 5 = 0

Since that isn't an equation, there is really nothing to solve.

It has two complex roots.

-x(x - 99)(X + 27) x = 0, -27, 99
