- 2 x^{3} - 3 x^{2} - 15 x + 11 = 0

x \approx 0.62333 \dots

Solution steps

- 2 x^{3} - 3 x^{2} - 15 x + 11 = 0

Find one solution for

- 2 x^{3} - 3 x^{2} - 15 x + 11 = 0

using Newton-Raphson:

x \approx 0.62333 \dots

Apply long division:

\frac{- 2 x ^{3} - 3 x ^{2} - 15 x + 11}{x - 0.62333 \dots} = - 2 x^{2} - 4.24666 \dots x - 17.64708 \dots

- 2 x^{2} - 4.24666 \dots x - 17.64708 \dots \approx 0

Find one solution for

- 2 x^{2} - 4.24666 \dots x - 17.64708 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx 0.62333 \dots

x, 2 x^{3} - 2 y^{3} = - 3

x^{4} + 6 x^{3} + 11 x^{2} + 6 x = 212520

x (x - 2) (3 x - 1) = 0

3 x^{3} - 2 x^{2} - 5 x = 0

175 = 5 x^{3}
