$x^{3} - 2 x^{2} + 4 = 3.6$

Step 1

Subtract $3.6$ from both sides of the equation.

$x^{3} - 2 x^{2} + 4 - 3.6 = 0$

Step 2

Subtract $3.6$ from $4$ .

$x^{3} - 2 x^{2} + 0.4 = 0$

Step 3

Graph each side of the equation. The solution is the x-value of the point of intersection.

$x \approx - 0.40760316, 0.51984866, 1.88775449$
