- 2 x^{3} - 2 x^{2} + 2 x + 8 = 0

x \approx 1.48558 \dots

Solution steps

- 2 x^{3} - 2 x^{2} + 2 x + 8 = 0

Find one solution for

- 2 x^{3} - 2 x^{2} + 2 x + 8 = 0

using Newton-Raphson:

x \approx 1.48558 \dots

Apply long division:

\frac{- 2 x ^{3} - 2 x ^{2} + 2 x + 8}{x - 1.48558 \dots} = - 2 x^{2} - 4.97116 \dots x - 5.38508 \dots

- 2 x^{2} - 4.97116 \dots x - 5.38508 \dots \approx 0

Find one solution for

- 2 x^{2} - 4.97116 \dots x - 5.38508 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx 1.48558 \dots

x^{4} - 4 x^{3} - x^{2} + 16 x - 12 = 0

x^{3} + x^{2} - 9 x - 9

x^{3} - 16 x^{2} + 75 x - 90 = 0

x, \frac{d ^{2} x}{d t ^{2}} = 2 x^{3}

x^{4} + 11 x^{2} = 0
