s^{3} + 3 s^{2} + 25 + 3 = 0

s \approx - 4.42802 \dots

Solution steps

s^{3} + 3 s^{2} + 25 + 3 = 0

Refine

s^{3} + 3 s^{2} + 28 = 0

Find one solution for

s^{3} + 3 s^{2} + 28 = 0

using Newton-Raphson:

s \approx - 4.42802 \dots

Apply long division:

\frac{s ^{3} + 3 s ^{2} + 28}{s + 4.42802 \dots} = s^{2} - 1.42802 \dots s + 6.32335 \dots

s^{2} - 1.42802 \dots s + 6.32335 \dots \approx 0

Find one solution for

s^{2} - 1.42802 \dots s + 6.32335 \dots = 0

using Newton-Raphson:

No Solution for

s \in R

The solution is

s \approx - 4.42802 \dots

15 x^{4} - 13 x^{2} - 2 = 0

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

2 a^{3} - 9 a^{2} - 4 = 0

(x - 2)^{3} = 64

m^{3} - 7 m - 6 = 0
