Question

What is the solution to the equation 4x + 2 = x3? (Round to the nearest tenth).

The solution is about x=?

Answer 1

X = -2

Explanation:

4x + 2 = x3

Subtract 2 from both sides: 4x = x3 -2

Subtract x3 from both sides: 4x - 3x = -2

This leaves 1x = -2 which can also be written as x = -2

x = -2
