solve for

x, 2 x^{3} + 4 x^{2} - 9 = 0

x \approx 1.18807 \dots

Solution steps

2 x^{3} + 4 x^{2} - 9 = 0

Find one solution for

2 x^{3} + 4 x^{2} - 9 = 0

using Newton-Raphson:

x \approx 1.18807 \dots

Apply long division:

\frac{2 x ^{3} + 4 x ^{2} - 9}{x - 1.18807 \dots} = 2 x^{2} + 6.37614 \dots x + 7.57530 \dots

2 x^{2} + 6.37614 \dots x + 7.57530 \dots \approx 0

Find one solution for

2 x^{2} + 6.37614 \dots x + 7.57530 \dots = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

x \approx 1.18807 \dots

- x^{3} + 9 x^{2} - 26 x + 24 = 0

x^{5} + 26 x^{3} - 36 = 0

z^{3} + z - 10 = 0

(x + 3)^{2} - (3 x - 1)^{2} = x^{3} + 4

3 t^{3} - 5 t^{2} - 2 t = 0
