P(z)=z^2-2z+3

Solution for P(z)=z^2-2z+3 equation:

Simplifying
P(z) = z2 + -2z + 3

Multiply P * z
zP = z2 + -2z + 3

Reorder the terms:
zP = 3 + -2z + z2

Solving
zP = 3 + -2z + z2

Solving for variable 'z'.

Reorder the terms:
-3 + 2z + zP + -1z2 = 3 + -2z + z2 + -3 + 2z + -1z2

Reorder the terms:
-3 + 2z + zP + -1z2 = 3 + -3 + -2z + 2z + z2 + -1z2

Combine like terms: 3 + -3 = 0
-3 + 2z + zP + -1z2 = 0 + -2z + 2z + z2 + -1z2
-3 + 2z + zP + -1z2 = -2z + 2z + z2 + -1z2

Combine like terms: -2z + 2z = 0
-3 + 2z + zP + -1z2 = 0 + z2 + -1z2
-3 + 2z + zP + -1z2 = z2 + -1z2

Combine like terms: z2 + -1z2 = 0
-3 + 2z + zP + -1z2 = 0
