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

x \approx 2.54681 \dots

Solution steps

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

Find one solution for

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

using Newton-Raphson:

x \approx 2.54681 \dots

Apply long division:

\frac{x ^{3} - 2 x ^{2} - x - 1}{x - 2.54681 \dots} = x^{2} + 0.54681 \dots x + 0.39264 \dots

x^{2} + 0.54681 \dots x + 0.39264 \dots \approx 0

Find one solution for

x^{2} + 0.54681 \dots x + 0.39264 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx 2.54681 \dots

z^{4} = 16

x^{6} + 65 x^{3} + 64 = 0

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

5 x^{4} - 5 = 0

2 x^{3} - x^{2} - 8 x + 4 = 0
