x^{3} + 7 x^{2} + 3 x + 8 = 0

x \approx - 6.73087 \dots

Solution steps

x^{3} + 7 x^{2} + 3 x + 8 = 0

Find one solution for

x^{3} + 7 x^{2} + 3 x + 8 = 0

using Newton-Raphson:

x \approx - 6.73087 \dots

Apply long division:

\frac{x ^{3} + 7 x ^{2} + 3 x + 8}{x + 6.73087 \dots} = x^{2} + 0.26912 \dots x + 1.18855 \dots

x^{2} + 0.26912 \dots x + 1.18855 \dots \approx 0

Find one solution for

x^{2} + 0.26912 \dots x + 1.18855 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx - 6.73087 \dots

\frac{y ( y - 1 ) ^{2}}{1.5} = 1

x^{3} - 13 x^{2} - 115 x + 138 = 0

z^{4} + 2 - 23 i = 0

0 = t^{3} - 6 t^{2} + 9 t + 5

x^{3} - x^{2} + 1 = - 6
