x^{4} + 4 x^{3} + 56 x^{2} + 64 x + 640 = 0

No Solution for x \in R

Solution steps

x^{4} + 4 x^{3} + 56 x^{2} + 64 x + 640 = 0

Find one solution for

x^{4} + 4 x^{3} + 56 x^{2} + 64 x + 640 = 0

using Newton-Raphson:

No Solution for

x \in R

The solution is

No Solution for x \in R

x^{5} + x^{3} - 6 x

z^{4} = - 16 i

x^{3} - 2 x^{2} - x + 2

12 x^{4} + 64 x^{3} + 59 x^{2} - 23 x - 12 = 0

x^{3} = 40
