Solving for variable 'T'.

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

Divide each side by '4'.
2.25 + -4T + T2 = 0

Move the constant term to the right:

Add '-2.25' to each side of the equation.
2.25 + -4T + -2.25 + T2 = 0 + -2.25

Reorder the terms:
2.25 + -2.25 + -4T + T2 = 0 + -2.25

Combine like terms: 2.25 + -2.25 = 0.00
0.00 + -4T + T2 = 0 + -2.25
-4T + T2 = 0 + -2.25

Combine like terms: 0 + -2.25 = -2.25
-4T + T2 = -2.25

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

Add '4' to each side of the equation.
-4T + 4 + T2 = -2.25 + 4

Reorder the terms:
4 + -4T + T2 = -2.25 + 4

Combine like terms: -2.25 + 4 = 1.75
4 + -4T + T2 = 1.75

Factor a perfect square on the left side:
(T + -2)(T + -2) = 1.75
