0 = 2 x^{3} + x - 5

x \approx 1.23477 \dots

Solution steps

0 = 2 x^{3} + x - 5

Switch sides

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

Find one solution for

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

using Newton-Raphson:

x \approx 1.23477 \dots

Apply long division:

\frac{2 x ^{3} + x - 5}{x - 1.23477 \dots} = 2 x^{2} + 2.46954 \dots x + 4.04932 \dots

2 x^{2} + 2.46954 \dots x + 4.04932 \dots \approx 0

Find one solution for

2 x^{2} + 2.46954 \dots x + 4.04932 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx 1.23477 \dots

x^{4} + 2 x^{3} + 4 x^{2} + 8 x + 16 = 0

0 = x^{4} - 12 x^{2} + 36

0 = x^{3} - 3 x^{2} - 5 x + 15

x^{4} - 7 x^{3} + 10 x^{2} - 2 x + 4 = 0

k^{3} = - 1
