Solve v^2-2v^3-v - ScanMath

Evaluate

v^{2} - 2 v^{3} - v

To find the roots of the expression,set the expression equal to 0

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

Factor the expression

v (v - 2 v^{2} - 1) = 0

Separate the equation into 2 possible cases

v = 0 v - 2 v^{2} - 1 = 0

Solve the equation

More Steps

v = 0 v = \frac{1}{4} + \frac{7}{4} i v = \frac{1}{4} - \frac{7}{4} i

Solution

v_{1} = \frac{1}{4} - \frac{7}{4} i, v_{2} = \frac{1}{4} + \frac{7}{4} i, v_{3} = 0

Alternative Form

v_{1} \approx 0.25 - 0.661438 i, v_{2} \approx 0.25 + 0.661438 i, v_{3} = 0
