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

x \approx - 1.22249 \dots

Solution steps

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

Move

4

to the left side

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

Find one solution for

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

using Newton-Raphson:

x \approx - 1.22249 \dots

Apply long division:

\frac{x ^{3} + x ^{2} + 3 x + 4}{x + 1.22249 \dots} = x^{2} - 0.22249 \dots x + 3.27199 \dots

x^{2} - 0.22249 \dots x + 3.27199 \dots \approx 0

Find one solution for

x^{2} - 0.22249 \dots x + 3.27199 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx - 1.22249 \dots

x^{8} + x^{4} + 1 = 0

d^{3} + 3 d^{2} + 8 d - 8 = 0

x^{3} + 3 x^{2} - 26 = 0

0.4 x - 2 \cdot 1 + 3 \cdot 5 = 0.7 x^{3}

(15 - x)^{3} = 64
