Solving for variable 't'.

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

Divide each side by '2'.
18 + -9.5t + t2 = 0

Move the constant term to the right:

Add '-18' to each side of the equation.
18 + -9.5t + -18 + t2 = 0 + -18

Reorder the terms:
18 + -18 + -9.5t + t2 = 0 + -18

Combine like terms: 18 + -18 = 0
0 + -9.5t + t2 = 0 + -18
-9.5t + t2 = 0 + -18

Combine like terms: 0 + -18 = -18
-9.5t + t2 = -18

The t term is -9.5t.  Take half its coefficient (-4.75).
Square it (22.5625) and add it to both sides.

Add '22.5625' to each side of the equation.
-9.5t + 22.5625 + t2 = -18 + 22.5625

Reorder the terms:
22.5625 + -9.5t + t2 = -18 + 22.5625

Combine like terms: -18 + 22.5625 = 4.5625
22.5625 + -9.5t + t2 = 4.5625
