5 x^{3} + 30 x^{2} + 45 = 0

x \approx - 6.23175 \dots

Solution steps

5 x^{3} + 30 x^{2} + 45 = 0

Find one solution for

5 x^{3} + 30 x^{2} + 45 = 0

using Newton-Raphson:

x \approx - 6.23175 \dots

Apply long division:

\frac{5 x ^{3} + 30 x ^{2} + 45}{x + 6.23175 \dots} = 5 x^{2} - 1.15875 \dots x + 7.22108 \dots

5 x^{2} - 1.15875 \dots x + 7.22108 \dots \approx 0

Find one solution for

5 x^{2} - 1.15875 \dots x + 7.22108 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx - 6.23175 \dots

12 x^{3} + 24 x^{2} = 0

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

2 x^{3} - 9 x + 8 = 0

- x^{4} - 4 x^{3} - 5 x^{2} - 2 = 0

f^{3} = f^{3} - 1 + f^{3} - 3
