4 - 3.6 x + 3.6 x^{2} - 1.2 x^{3} = 0

x \approx 2.32635 \dots

Solution steps

4 - 3.6 x + 3.6 x^{2} - 1.2 x^{3} = 0

Multiply both sides by

10

40 - 36 x + 36 x^{2} - 12 x^{3} = 0

Write in the standard form

a_{n} x^{n} + \dots + a_{1} x + a_{0} = 0

- 12 x^{3} + 36 x^{2} - 36 x + 40 = 0

Find one solution for

- 12 x^{3} + 36 x^{2} - 36 x + 40 = 0

using Newton-Raphson:

x \approx 2.32635 \dots

Apply long division:

\frac{- 12 x ^{3} + 36 x ^{2} - 36 x + 40}{x - 2.32635 \dots} = - 12 x^{2} + 8.08377 \dots x - 17.19429 \dots

- 12 x^{2} + 8.08377 \dots x - 17.19429 \dots \approx 0

Find one solution for

- 12 x^{2} + 8.08377 \dots x - 17.19429 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx 2.32635 \dots

4 x^{3} - 12 x^{2} + 11 x - 3 = 0

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

y^{3} - 10 y^{2} + 21 y = 0

x^{6} - x^{3} + 1 = 0

s^{3} + 9 s^{2} + 15 s + 5 = 0
