z^2-z-i+1=0

Solution for z^2-z-i+1=0 equation:

Simplifying
z2 + -1z + -1i + 1 = 0

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

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

Solving for variable 'i'.

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

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

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

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

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

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

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

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

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

Divide each side by '-1'.
i = 1 + -1z + z2

Simplifying
i = 1 + -1z + z2
