Solving for variable 'z'.

Begin completing the square.

Move the constant term to the right:

Add '-5' to each side of the equation.
5 + 4z + -5 + z2 = 0 + -5

Reorder the terms:
5 + -5 + 4z + z2 = 0 + -5

Combine like terms: 5 + -5 = 0
0 + 4z + z2 = 0 + -5
4z + z2 = 0 + -5

Combine like terms: 0 + -5 = -5
4z + z2 = -5

The z term is 4z.  Take half its coefficient (2).
Square it (4) and add it to both sides.

Add '4' to each side of the equation.
4z + 4 + z2 = -5 + 4

Reorder the terms:
4 + 4z + z2 = -5 + 4

Combine like terms: -5 + 4 = -1
4 + 4z + z2 = -1

Factor a perfect square on the left side:
(z + 2)(z + 2) = -1
