- x^{3} + 4 x^{2} - 9 x - 6 = 0

x \approx - 0.52698 \dots

Solution steps

- x^{3} + 4 x^{2} - 9 x - 6 = 0

Find one solution for

- x^{3} + 4 x^{2} - 9 x - 6 = 0

using Newton-Raphson:

x \approx - 0.52698 \dots

Apply long division:

\frac{- x ^{3} + 4 x ^{2} - 9 x - 6}{x + 0.52698 \dots} = - x^{2} + 4.52698 \dots x - 11.38562 \dots

- x^{2} + 4.52698 \dots x - 11.38562 \dots \approx 0

Find one solution for

- x^{2} + 4.52698 \dots x - 11.38562 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx - 0.52698 \dots

z^{4} = - 1 + 3 i

x = - 1.3 x^{3} - 4 x^{2} - 13 x - 6

(\frac{1}{5}) x^{5} = 1

8 x^{12} = 6 x + 4

2 x - 712 - 4 - x^{6} = 1920
