x^{3} + 3 x + 8 = 0

x \approx - 1.51274 \dots

Solution steps

x^{3} + 3 x + 8 = 0

Find one solution for

x^{3} + 3 x + 8 = 0

using Newton-Raphson:

x \approx - 1.51274 \dots

Apply long division:

\frac{x ^{3} + 3 x + 8}{x + 1.51274 \dots} = x^{2} - 1.51274 \dots x + 5.28839 \dots

x^{2} - 1.51274 \dots x + 5.28839 \dots \approx 0

Find one solution for

x^{2} - 1.51274 \dots x + 5.28839 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx - 1.51274 \dots

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

p^{4} + 40 = 14 p^{2}

m^{4} + m^{3} + m^{2} = 0

x^{3} + 3 x^{2} - 24 x - 72 = 0

5 x^{3} + x^{2} - 20 x - 4 = 0
