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

x \approx 0.43232 \dots, x \approx 1.32001 \dots, x \approx - 1.75233 \dots

Solution steps

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

Find one solution for

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

using Newton-Raphson:

x \approx 0.43232 \dots

Apply long division:

\frac{2 x ^{3} - 5 x + 2}{x - 0.43232 \dots} = 2 x^{2} + 0.86464 \dots x - 4.62619 \dots

2 x^{2} + 0.86464 \dots x - 4.62619 \dots \approx 0

Find one solution for

2 x^{2} + 0.86464 \dots x - 4.62619 \dots = 0

using Newton-Raphson:

x \approx 1.32001 \dots

Apply long division:

\frac{2 x ^{2} + 0.86464 \dots x - 4.62619 \dots}{x - 1.32001 \dots} = 2 x + 3.50466 \dots

2 x + 3.50466 \dots \approx 0

x \approx - 1.75233 \dots

The solutions are

x \approx 0.43232 \dots, x \approx 1.32001 \dots, x \approx - 1.75233 \dots

4 x^{4} - 19 x^{2} + 12 = 0

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

2 x^{3} + 6 x^{2} + 5 x + 15 = 0

- 9 m^{3} + 18 m^{2} - 8 m = 0

x, (x - 3)^{3} = 8 (y - 2)
