Solution for z^2+(2-i)z-i=0 equation:


Simplifying
z2 + (2 + -1i) * z + -1i = 0

Reorder the terms for easier multiplication:
z2 + z(2 + -1i) + -1i = 0
z2 + (2 * z + -1i * z) + -1i = 0

Reorder the terms:
z2 + (-1iz + 2z) + -1i = 0
z2 + (-1iz + 2z) + -1i = 0

Reorder the terms:
-1i + -1iz + 2z + z2 = 0

Solving
-1i + -1iz + 2z + z2 = 0

Solving for variable 'i'.

Move all terms containing i to the left, all other terms to the right.

Add '-2z' to each side of the equation.
-1i + -1iz + 2z + -2z + z2 = 0 + -2z

Combine like terms: 2z + -2z = 0
-1i + -1iz + 0 + z2 = 0 + -2z
-1i + -1iz + z2 = 0 + -2z
Remove the zero:
-1i + -1iz + z2 = -2z

Add '-1z2' to each side of the equation.
-1i + -1iz + z2 + -1z2 = -2z + -1z2

Combine like terms: z2 + -1z2 = 0
-1i + -1iz + 0 = -2z + -1z2
-1i + -1iz = -2z + -1z2

Reorder the terms:
-1i + -1iz + 2z + z2 = -2z + 2z + -1z2 + z2

Combine like terms: -2z + 2z = 0
-1i + -1iz + 2z + z2 = 0 + -1z2 + z2
-1i + -1iz + 2z + z2 = -1z2 + z2

Combine like terms: -1z2 + z2 = 0
-1i + -1iz + 2z + z2 = 0

The solution to this equation could not be determined.
