x^{3} + 4 x = 8

x \approx 1.36465 \dots

Solution steps

x^{3} + 4 x = 8

Move

8

to the left side

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

Find one solution for

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

using Newton-Raphson:

x \approx 1.36465 \dots

Apply long division:

\frac{x ^{3} + 4 x - 8}{x - 1.36465 \dots} = x^{2} + 1.36465 \dots x + 5.86228 \dots

x^{2} + 1.36465 \dots x + 5.86228 \dots \approx 0

Find one solution for

x^{2} + 1.36465 \dots x + 5.86228 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx 1.36465 \dots

3 x^{4} - 74 x^{2} - 25 = 0

114 s^{5} = 1.34 \cdot 1 0^{- 34}

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

- 50 = 10 b^{10} b

0.195618 = (1 + x)^{12} - 1
