0 = x^{3} - 2 x - 2

x \approx 1.76929 \dots

Solution steps

0 = x^{3} - 2 x - 2

Switch sides

x^{3} - 2 x - 2 = 0

Find one solution for

x^{3} - 2 x - 2 = 0

using Newton-Raphson:

x \approx 1.76929 \dots

Apply long division:

\frac{x ^{3} - 2 x - 2}{x - 1.76929 \dots} = x^{2} + 1.76929 \dots x + 1.13039 \dots

x^{2} + 1.76929 \dots x + 1.13039 \dots \approx 0

Find one solution for

x^{2} + 1.76929 \dots x + 1.13039 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx 1.76929 \dots

- x^{3} + 9 x - 5 = 0

n^{4} + 2 n^{3} + n^{2} + 20 n = 400

z^{4} - 4 i = 0

3 x^{4} - 6 x^{2} - 72 = 0

b^{3} - 16 b = 0
