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

x \approx 0.91310 \dots, x \approx - 2.25980 \dots

Solution steps

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

Find one solution for

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

using Newton-Raphson:

x \approx 0.91310 \dots

Apply long division:

\frac{x ^{4} + 8 x - 8}{x - 0.91310 \dots} = x^{3} + 0.91310 \dots x^{2} + 0.83376 \dots x + 8.76131 \dots

x^{3} + 0.91310 \dots x^{2} + 0.83376 \dots x + 8.76131 \dots \approx 0

Find one solution for

x^{3} + 0.91310 \dots x^{2} + 0.83376 \dots x + 8.76131 \dots = 0

using Newton-Raphson:

x \approx - 2.25980 \dots

Apply long division:

\frac{x ^{3} + 0.91310 \dots x ^{2} + 0.83376 \dots x + 8.76131 \dots}{x + 2.25980 \dots} = x^{2} - 1.34669 \dots x + 3.87702 \dots

x^{2} - 1.34669 \dots x + 3.87702 \dots \approx 0

Find one solution for

x^{2} - 1.34669 \dots x + 3.87702 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solutions are

x \approx 0.91310 \dots, x \approx - 2.25980 \dots

x^{4} - 4 x^{3} - 7 x^{2} + 22 x + 24 = 0

z^{3} = - 2

200 x^{3} + 190 x^{2} + 47 x = 0

14 - a^{2} a = - 3

2 = y + y^{3}
