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

x \approx 0.53778 \dots

Solution steps

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

Find one solution for

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

using Newton-Raphson:

x \approx 0.53778 \dots

Apply long division:

\frac{2 x ^{3} + 5 x - 3}{x - 0.53778 \dots} = 2 x^{2} + 1.07557 \dots x + 5.57842 \dots

2 x^{2} + 1.07557 \dots x + 5.57842 \dots \approx 0

Find one solution for

2 x^{2} + 1.07557 \dots x + 5.57842 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx 0.53778 \dots

2 x^{4} - 50 x^{2} = 0

2 x^{3} - x^{2} - 18 x + 9 = 0

- x^{3} + 5 x^{2} - 8 x + 4 = 0

x^{4} = 625

20 = [5 + \frac{0.12 x}{10}]^{20}
