2 x^{3} - 54 x - 6 = 0

x \approx - 0.11116 \dots, x \approx - 5.13967 \dots, x \approx 5.25084 \dots

Solution steps

2 x^{3} - 54 x - 6 = 0

Find one solution for

2 x^{3} - 54 x - 6 = 0

using Newton-Raphson:

x \approx - 0.11116 \dots

Apply long division:

\frac{2 x ^{3} - 54 x - 6}{x + 0.11116 \dots} = 2 x^{2} - 0.22232 \dots x - 53.97528 \dots

2 x^{2} - 0.22232 \dots x - 53.97528 \dots \approx 0

Find one solution for

2 x^{2} - 0.22232 \dots x - 53.97528 \dots = 0

using Newton-Raphson:

x \approx - 5.13967 \dots

Apply long division:

\frac{2 x ^{2} - 0.22232 \dots x - 53.97528 \dots}{x + 5.13967 \dots} = 2 x - 10.50168 \dots

2 x - 10.50168 \dots \approx 0

x \approx 5.25084 \dots

The solutions are

x \approx - 0.11116 \dots, x \approx - 5.13967 \dots, x \approx 5.25084 \dots

x^{10} \cdot (- 20) = 100

xxx = 27

f^{3} = - 216

x^{6} = 384

x^{2} + x^{4} = 20
