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

x \approx 2.00994 \dots

Solution steps

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

Multiply both sides by

10

91 = 10 x^{3} - 20 x + 50

Switch sides

10 x^{3} - 20 x + 50 = 91

Move

91

to the left side

10 x^{3} - 20 x - 41 = 0

Find one solution for

10 x^{3} - 20 x - 41 = 0

using Newton-Raphson:

x \approx 2.00994 \dots

Apply long division:

\frac{10 x ^{3} - 20 x - 41}{x - 2.00994 \dots} = 10 x^{2} + 20.09940 \dots x + 20.39861 \dots

10 x^{2} + 20.09940 \dots x + 20.39861 \dots \approx 0

Find one solution for

10 x^{2} + 20.09940 \dots x + 20.39861 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx 2.00994 \dots

25 b^{2} + 35 b^{4} = 45 b^{5}

12 x^{3} + 13 x^{2} + x = 0

2 x^{3} - 5 x^{2} + 6 x + 27 = 0

2 x^{3} + 7 x^{2} + 7 x + 2 = 0

3 c^{3} + 21 c^{2} - 54 c = 0
