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

x \approx - 2.28427 \dots

Solution steps

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

Find one solution for

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

using Newton-Raphson:

x \approx - 2.28427 \dots

Apply long division:

\frac{x ^{3} - x ^{2} - 4 x + 8}{x + 2.28427 \dots} = x^{2} - 3.28427 \dots x + 3.50220 \dots

x^{2} - 3.28427 \dots x + 3.50220 \dots \approx 0

Find one solution for

x^{2} - 3.28427 \dots x + 3.50220 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx - 2.28427 \dots

v^{4} - 0.8949 v^{2} + 0.028367 = 0

x, x^{3} + 5 y = 25

4 x^{3} + 12 a x^{2} - 16 a^{2} x = 0

x^{4} - 2 x^{3} - 8 x + 16 = 0

x^{3} - 8 x = 2 x^{2}
