- x^{3} + 9 x - 5 = 0

x \approx 0.57688 \dots, x \approx 2.66966 \dots, x \approx - 3.24655 \dots

Solution steps

- x^{3} + 9 x - 5 = 0

Find one solution for

- x^{3} + 9 x - 5 = 0

using Newton-Raphson:

x \approx 0.57688 \dots

Apply long division:

\frac{- x ^{3} + 9 x - 5}{x - 0.57688 \dots} = - x^{2} - 0.57688 \dots x + 8.66720 \dots

- x^{2} - 0.57688 \dots x + 8.66720 \dots \approx 0

Find one solution for

- x^{2} - 0.57688 \dots x + 8.66720 \dots = 0

using Newton-Raphson:

x \approx 2.66966 \dots

Apply long division:

\frac{- x ^{2} - 0.57688 \dots x + 8.66720 \dots}{x - 2.66966 \dots} = - x - 3.24655 \dots

- x - 3.24655 \dots \approx 0

x \approx - 3.24655 \dots

The solutions are

x \approx 0.57688 \dots, x \approx 2.66966 \dots, x \approx - 3.24655 \dots

n^{4} + 2 n^{3} + n^{2} + 20 n = 400

z^{4} - 4 i = 0

3 x^{4} - 6 x^{2} - 72 = 0

b^{3} - 16 b = 0

8 x^{4} - 4 x^{2} = 0
