- 2 x^{3} - 6 x^{2} - 6 x - 5 = 0

x \approx - 2.14471 \dots

Solution steps

- 2 x^{3} - 6 x^{2} - 6 x - 5 = 0

Find one solution for

- 2 x^{3} - 6 x^{2} - 6 x - 5 = 0

using Newton-Raphson:

x \approx - 2.14471 \dots

Apply long division:

\frac{- 2 x ^{3} - 6 x ^{2} - 6 x - 5}{x + 2.14471 \dots} = - 2 x^{2} - 1.71057 \dots x - 2.33131 \dots

- 2 x^{2} - 1.71057 \dots x - 2.33131 \dots \approx 0

Find one solution for

- 2 x^{2} - 1.71057 \dots x - 2.33131 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx - 2.14471 \dots

x^{100} - 1 = 0

x^{3} + 3 x^{2} + 0.25 x + 4 = 0

x^{4} - 6 x^{3} + 7 x^{2} - 6 x + 1 = 0

- a^{3} + 6 a^{2} - 11 a + 6 = 0

3 x^{3} - 3 x = 0
