70 x^{3} + 24 x^{2} - 10 x + 20 = 0

x \approx - 0.87711 \dots

Solution steps

70 x^{3} + 24 x^{2} - 10 x + 20 = 0

Find one solution for

70 x^{3} + 24 x^{2} - 10 x + 20 = 0

using Newton-Raphson:

x \approx - 0.87711 \dots

Apply long division:

\frac{70 x ^{3} + 24 x ^{2} - 10 x + 20}{x + 0.87711 \dots} = 70 x^{2} - 37.39784 \dots x + 22.80210 \dots

70 x^{2} - 37.39784 \dots x + 22.80210 \dots \approx 0
