3 x^{3} - 19 x - 5 = 0

x \approx - 0.26613 \dots, x \approx - 2.37296 \dots, x \approx 2.63910 \dots

Solution steps

3 x^{3} - 19 x - 5 = 0

Find one solution for

3 x^{3} - 19 x - 5 = 0

using Newton-Raphson:

x \approx - 0.26613 \dots

Apply long division:

\frac{3 x ^{3} - 19 x - 5}{x + 0.26613 \dots} = 3 x^{2} - 0.79840 \dots x - 18.78751 \dots

3 x^{2} - 0.79840 \dots x - 18.78751 \dots \approx 0

Find one solution for

3 x^{2} - 0.79840 \dots x - 18.78751 \dots = 0

using Newton-Raphson:

x \approx - 2.37296 \dots

Apply long division:

\frac{3 x ^{2} - 0.79840 \dots x - 18.78751 \dots}{x + 2.37296 \dots} = 3 x - 7.91730 \dots

3 x - 7.91730 \dots \approx 0

x \approx 2.63910 \dots

The solutions are

x \approx - 0.26613 \dots, x \approx - 2.37296 \dots, x \approx 2.63910 \dots

x^{4} - 7 x^{2} - 8 = 0

2 x^{3} - 12 x^{2} + 18 = 0

m^{3} + 3 m^{2} + 3 = 0

y^{3} + y = 16

y^{3} - 3 y - 2 = 0
