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

x \approx - 0.54368 \dots

Solution steps

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

Find one solution for

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

using Newton-Raphson:

x \approx - 0.54368 \dots

Apply long division:

\frac{- x ^{3} + x ^{2} - x - 1}{x + 0.54368 \dots} = - x^{2} + 1.54368 \dots x - 1.83928 \dots

- x^{2} + 1.54368 \dots x - 1.83928 \dots \approx 0

Find one solution for

- x^{2} + 1.54368 \dots x - 1.83928 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx - 0.54368 \dots

9 x^{3} = 4 x^{2}

15651.63 = 3000 (1 + x)^{3}

9 w^{2} + 17 w + 12 = 3 w^{2} 3 w^{2}

x + x^{2} - x^{4} + x^{8} = 125

s^{3} + 6 s^{2} + 5 s + 30 = 0
