x^{3} + x^{2} + 17 x - 15 = 0

x \approx 0.81206 \dots

Solution steps

x^{3} + x^{2} + 17 x - 15 = 0

Find one solution for

x^{3} + x^{2} + 17 x - 15 = 0

using Newton-Raphson:

x \approx 0.81206 \dots

Apply long division:

\frac{x ^{3} + x ^{2} + 17 x - 15}{x - 0.81206 \dots} = x^{2} + 1.81206 \dots x + 18.47150 \dots

x^{2} + 1.81206 \dots x + 18.47150 \dots \approx 0

Find one solution for

x^{2} + 1.81206 \dots x + 18.47150 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx 0.81206 \dots

(x + 4)^{3} - 72 = 0

x^{3} + 7.8 x^{2} - 0.0844 = 0

x^{4} + 4 x^{3} - 8 x = 0

a^{8} - 17 a^{4} + 16 = 0

24 x^{4} + 16 x^{3} - 3 x - 2 = 0
