5 x^{3} - 29 x + 30 = 0

x \approx - 2.81612 \dots

Solution steps

5 x^{3} - 29 x + 30 = 0

Find one solution for

5 x^{3} - 29 x + 30 = 0

using Newton-Raphson:

x \approx - 2.81612 \dots

Apply long division:

\frac{5 x ^{3} - 29 x + 30}{x + 2.81612 \dots} = 5 x^{2} - 14.08064 \dots x + 10.65292 \dots

5 x^{2} - 14.08064 \dots x + 10.65292 \dots \approx 0

Find one solution for

5 x^{2} - 14.08064 \dots x + 10.65292 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx - 2.81612 \dots

- x^{3} + 3 x^{2} - 24 x + 1 = 0

x^{3} - 8 x^{2} + 21 x - 18 x = 0

- x^{3} + 3 x + (2 - 2) \cdot x^{2} - 2 = 0

z^{3} = - 8 i

x^{3} - 5 x^{2} + 7 x + 13 = 0
