4 s^{3} + 7 s^{3} - 20 s - 35 = 0

s \approx 1.87489 \dots

Solution steps

4 s^{3} + 7 s^{3} - 20 s - 35 = 0

Refine

11 s^{3} - 20 s - 35 = 0

Find one solution for

11 s^{3} - 20 s - 35 = 0

using Newton-Raphson:

s \approx 1.87489 \dots

Apply long division:

\frac{11 s ^{3} - 20 s - 35}{s - 1.87489 \dots} = 11 s^{2} + 20.62388 \dots s + 18.66767 \dots

11 s^{2} + 20.62388 \dots s + 18.66767 \dots \approx 0

Find one solution for

11 s^{2} + 20.62388 \dots s + 18.66767 \dots = 0

using Newton-Raphson:

No Solution for

s \in R

The solution is

s \approx 1.87489 \dots

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

z^{3} + 1 = e^{\frac{π}{2} i}

2 (x^{2} - 2 x)^{2} - 5 (x^{2} - 2 x) = 12

x^{4} - 5 x^{2} - 50 = 0

t = - 3.9 (t)^{2} - (t)^{4}
