x^{3} - 3 x^{2} - 24 x + 90 = 0

x \approx - 5.12022 \dots

Solution steps

x^{3} - 3 x^{2} - 24 x + 90 = 0

Find one solution for

x^{3} - 3 x^{2} - 24 x + 90 = 0

using Newton-Raphson:

x \approx - 5.12022 \dots

Apply long division:

\frac{x ^{3} - 3 x ^{2} - 24 x + 90}{x + 5.12022 \dots} = x^{2} - 8.12022 \dots x + 17.57735 \dots

x^{2} - 8.12022 \dots x + 17.57735 \dots \approx 0

Find one solution for

x^{2} - 8.12022 \dots x + 17.57735 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx - 5.12022 \dots

a^{15} = \frac{1}{4}

x, x^{6} - 8 x^{3} - 9 = 0

(- 20 b^{4}) \cdot (b b^{2} b) = 0

x = 3.25 x^{3} - 6 x^{2} + 7 x - 88

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