x^{3} + x = 16

x \approx 2.38768 \dots

Solution steps

x^{3} + x = 16

Move

16

to the left side

x^{3} + x - 16 = 0

Find one solution for

x^{3} + x - 16 = 0

using Newton-Raphson:

x \approx 2.38768 \dots

Apply long division:

\frac{x ^{3} + x - 16}{x - 2.38768 \dots} = x^{2} + 2.38768 \dots x + 6.70104 \dots

x^{2} + 2.38768 \dots x + 6.70104 \dots \approx 0

Find one solution for

x^{2} + 2.38768 \dots x + 6.70104 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx 2.38768 \dots

\frac{35 x ^{15}}{2} = \frac{( x + 70 )}{14 - 40}

7 x^{3} - 168 x^{2} + 2048 = 0

2 x^{24} x - 16 = 2

25 = 15 (1 + r)^{5}

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