- x^{3} - x^{2} + 8 x - 12 = 0

x \approx - 3.86918 \dots

Solution steps

- x^{3} - x^{2} + 8 x - 12 = 0

Find one solution for

- x^{3} - x^{2} + 8 x - 12 = 0

using Newton-Raphson:

x \approx - 3.86918 \dots

Apply long division:

\frac{- x ^{3} - x ^{2} + 8 x - 12}{x + 3.86918 \dots} = - x^{2} + 2.86918 \dots x - 3.10142 \dots

- x^{2} + 2.86918 \dots x - 3.10142 \dots \approx 0

Find one solution for

- x^{2} + 2.86918 \dots x - 3.10142 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx - 3.86918 \dots

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

- 4 (x - 8)^{3} = 0

(x^{12} - 1) 8 = x^{84} - 1

w^{3} = - 12

x^{3} + 5 x^{2} + 7 x = 0
