- 7 x^{3} - 6 x = 8

x \approx - 0.77990 \dots

Solution steps

- 7 x^{3} - 6 x = 8

Move

8

to the left side

- 7 x^{3} - 6 x - 8 = 0

Find one solution for

- 7 x^{3} - 6 x - 8 = 0

using Newton-Raphson:

x \approx - 0.77990 \dots

Apply long division:

\frac{- 7 x ^{3} - 6 x - 8}{x + 0.77990 \dots} = - 7 x^{2} + 5.45930 \dots x - 10.25771 \dots

- 7 x^{2} + 5.45930 \dots x - 10.25771 \dots \approx 0

Find one solution for

- 7 x^{2} + 5.45930 \dots x - 10.25771 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx - 0.77990 \dots

(x - 2)^{3} + 3 x^{2} = (x - 1)^{2} + 2

(r - 1) (r + 1)^{4} = 0

a^{3} + a^{2} = 64 a + 64

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

y^{4} - 5 y^{2} - 36 = 0
