Begin completing the square.  Divide all terms by
4 the coefficient of the squared term: 

Divide each side by '4'.
7.25 + -6z + z2 = 0

Move the constant term to the right:

Add '-7.25' to each side of the equation.
7.25 + -6z + -7.25 + z2 = 0 + -7.25

Reorder the terms:
7.25 + -7.25 + -6z + z2 = 0 + -7.25

Combine like terms: 7.25 + -7.25 = 0.00
0.00 + -6z + z2 = 0 + -7.25
-6z + z2 = 0 + -7.25

Combine like terms: 0 + -7.25 = -7.25
-6z + z2 = -7.25

The z term is -6z.  Take half its coefficient (-3).
Square it (9) and add it to both sides.
