Solving for variable 't'.

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

Divide each side by '25'.
3.48 + 3.6t + t2 = 0

Move the constant term to the right:

Add '-3.48' to each side of the equation.
3.48 + 3.6t + -3.48 + t2 = 0 + -3.48

Reorder the terms:
3.48 + -3.48 + 3.6t + t2 = 0 + -3.48

Combine like terms: 3.48 + -3.48 = 0.00
0.00 + 3.6t + t2 = 0 + -3.48
3.6t + t2 = 0 + -3.48

Combine like terms: 0 + -3.48 = -3.48
3.6t + t2 = -3.48

The t term is 3.6t.  Take half its coefficient (1.8).
Square it (3.24) and add it to both sides.

Add '3.24' to each side of the equation.
3.6t + 3.24 + t2 = -3.48 + 3.24

Reorder the terms:
3.24 + 3.6t + t2 = -3.48 + 3.24

Combine like terms: -3.48 + 3.24 = -0.24
3.24 + 3.6t + t2 = -0.24

Factor a perfect square on the left side:
(t + 1.8)(t + 1.8) = -0.24
