x^{3} + 6 x = 25

x \approx 2.25515 \dots

Solution steps

x^{3} + 6 x = 25

Move

25

to the left side

x^{3} + 6 x - 25 = 0

Find one solution for

x^{3} + 6 x - 25 = 0

using Newton-Raphson:

x \approx 2.25515 \dots

Apply long division:

\frac{x ^{3} + 6 x - 25}{x - 2.25515 \dots} = x^{2} + 2.25515 \dots x + 11.08571 \dots

x^{2} + 2.25515 \dots x + 11.08571 \dots \approx 0

Find one solution for

x^{2} + 2.25515 \dots x + 11.08571 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx 2.25515 \dots

- k^{3} + 3 k - 2 = 0

x^{6} = 100

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

3 x^{4} + 16 x^{3} + 32 x^{2} + 27 x + 6

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