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 + -7.5t + t2 = 0

Move the constant term to the right:

Add '-18' to each side of the equation.
18 + -7.5t + -18 + t2 = 0 + -18

Reorder the terms:
18 + -18 + -7.5t + t2 = 0 + -18

Combine like terms: 18 + -18 = 0
0 + -7.5t + t2 = 0 + -18
-7.5t + t2 = 0 + -18

Combine like terms: 0 + -18 = -18
-7.5t + t2 = -18

The t term is -7.5t.  Take half its coefficient (-3.75).
Square it (14.0625) and add it to both sides.

Add '14.0625' to each side of the equation.
-7.5t + 14.0625 + t2 = -18 + 14.0625

Reorder the terms:
14.0625 + -7.5t + t2 = -18 + 14.0625

Combine like terms: -18 + 14.0625 = -3.9375
14.0625 + -7.5t + t2 = -3.9375

Factor a perfect square on the left side:
(t + -3.75)(t + -3.75) = -3.9375

Can't calculate square root of the right side.
