w^{3} - 2 w^{2} + w - 2 = 0.2

w \approx 2.03878 \dots

Solution steps

w^{3} - 2 w^{2} + w - 2 = 0.2

Multiply both sides by

10

10 w^{3} - 20 w^{2} + 10 w - 20 = 2

Move

2

to the left side

10 w^{3} - 20 w^{2} + 10 w - 22 = 0

Find one solution for

10 w^{3} - 20 w^{2} + 10 w - 22 = 0

using Newton-Raphson:

w \approx 2.03878 \dots

Apply long division:

\frac{10 w ^{3} - 20 w ^{2} + 10 w - 22}{w - 2.03878 \dots} = 10 w^{2} + 0.38784 \dots w + 10.79074 \dots

10 w^{2} + 0.38784 \dots w + 10.79074 \dots \approx 0

Find one solution for

10 w^{2} + 0.38784 \dots w + 10.79074 \dots = 0

using Newton-Raphson:

No Solution for

w \in R

The solution is

w \approx 2.03878 \dots

- 4 x^{5} + 32 x^{3} + 192 x = 0

- 2 x^{3} - x^{2} + 8 x - 5 = 0

(x^{3}) (x + 3) = 5

0 = 12 x^{3} - 12 x^{2}

y^{3} + 5 y^{2} - 49 y - 245 = 0
