x^{3} - 2 x - 5 = 0, (x = 2.0813)

No Solution for x \in R

Solution steps

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

Find one solution for

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

using Newton-Raphson:

x \approx 2.09455 \dots

Apply long division:

\frac{x ^{3} - 2 x - 5}{x - 2.09455 \dots} = x^{2} + 2.09455 \dots x + 2.38714 \dots

x^{2} + 2.09455 \dots x + 2.38714 \dots \approx 0

Find one solution for

x^{2} + 2.09455 \dots x + 2.38714 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx 2.09455 \dots

Check constrains

No Solution for x \in R

(x - \frac{1}{3}) (x^{2} + x \frac{0.1}{3} + \frac{1 ^{2}}{3 ^{2}}) = 64

(x - 7)^{4} = (x - 7)^{5}

x^{3} = - 125

(x + 5) (x^{2} - 4) = 0

(x^{2} - 5 x)^{2} - 7 (x^{2} - 5 x) + 6 = 0
