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

x \approx 4.80738 \dots

Solution steps

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

Find one solution for

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

using Newton-Raphson:

x \approx 4.80738 \dots

Apply long division:

\frac{x ^{3} - 2 x ^{2} - 11 x - 12}{x - 4.80738 \dots} = x^{2} + 2.80738 \dots x + 2.49616 \dots

x^{2} + 2.80738 \dots x + 2.49616 \dots \approx 0

Find one solution for

x^{2} + 2.80738 \dots x + 2.49616 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx 4.80738 \dots

z^{6} - (3 + 2 i) z^{3} + 2 + 2 i = 0

16 x^{4} - x^{2} = 0

x^{3} - 3 x^{2} - 10 x + 24

\frac{Q ^{3}}{3} - 10 Q^{2} + 80 Q + 648 = 4 Q

x^{3} + x^{2} - 17 x + 15
