roots

- x^{3} + 4 x^{2} - 9 x - 6

x \approx - 0.52698 \dots

Solution steps

- x^{3} + 4 x^{2} - 9 x - 6

The roots are the intercepts with the x-axis

(y = 0)

- x^{3} + 4 x^{2} - 9 x - 6 = 0

Find one solution for

- x^{3} + 4 x^{2} - 9 x - 6 = 0

using Newton-Raphson:

x \approx - 0.52698 \dots

Apply long division:

\frac{- x ^{3} + 4 x ^{2} - 9 x - 6}{x + 0.52698 \dots} = - x^{2} + 4.52698 \dots x - 11.38562 \dots

- x^{2} + 4.52698 \dots x - 11.38562 \dots \approx 0

Find one solution for

- x^{2} + 4.52698 \dots x - 11.38562 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx - 0.52698 \dots

12 x^{3} - 20 x^{2} + x + 3

0 = 12 t^{3} - 48 t^{2} + 48 t

24 x^{3} - 3 = 0

x^{4} + 62 x^{2} + 128 x + 65 = 0

x^{3} - 11 x^{2} + 26 x - 16 = 0
