z^2+2z+c=

Solution for z^2+2z+c= equation:

Simplifying
z2 + 2z + c = 0

Reorder the terms:
c + 2z + z2 = 0

Solving
c + 2z + z2 = 0

Solving for variable 'c'.

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

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

Combine like terms: 2z + -2z = 0
c + 0 + z2 = 0 + -2z
c + z2 = 0 + -2z
Remove the zero:
c + z2 = -2z

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

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

Simplifying
c = -2z + -1z2
