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

x \approx - 5.15077 \dots

Solution steps

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

Find one solution for

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

using Newton-Raphson:

x \approx - 5.15077 \dots

Apply long division:

\frac{x ^{3} + 5 x ^{2} + 4}{x + 5.15077 \dots} = x^{2} - 0.15077 \dots x + 0.77658 \dots

x^{2} - 0.15077 \dots x + 0.77658 \dots \approx 0

Find one solution for

x^{2} - 0.15077 \dots x + 0.77658 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx - 5.15077 \dots

x^{4} + 12 x^{3} + 44 x^{2} + 48 x = 3465

x^{2} 16 x + 64 = 0

127 + 5 x + 3 + 10 x^{7} + 88 = 360

x^{3} - 3 x^{2} - 28 x + 60 = 0

35 = \frac{x ^{2} ( 4 x + 6 )}{2}
