x^{3} + 2 x + 1 x = 3

x \approx 0.81773 \dots

Solution steps

x^{3} + 2 x + 1 \cdot x = 3

Refine

x^{3} + 3 x = 3

Move

3

to the left side

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

Find one solution for

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

using Newton-Raphson:

x \approx 0.81773 \dots

Apply long division:

\frac{x ^{3} + 3 x - 3}{x - 0.81773 \dots} = x^{2} + 0.81773 \dots x + 3.66868 \dots

x^{2} + 0.81773 \dots x + 3.66868 \dots \approx 0

Find one solution for

x^{2} + 0.81773 \dots x + 3.66868 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx 0.81773 \dots

9 x^{4} + 82 x^{2} + 9 = 0

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

25 x^{4} - 26 x^{2} + 1 = 0

x^{3} - 3 x^{2} - 33 x + 35 = 0

8 = u^{3}
