-0.1875 + 0.1875 + -2.5t + t2 = 0 + 0.1875

Combine like terms: -0.1875 + 0.1875 = 0.0000
0.0000 + -2.5t + t2 = 0 + 0.1875
-2.5t + t2 = 0 + 0.1875

Combine like terms: 0 + 0.1875 = 0.1875
-2.5t + t2 = 0.1875

The t term is -2.5t.  Take half its coefficient (-1.25).
Square it (1.5625) and add it to both sides.

Add '1.5625' to each side of the equation.
-2.5t + 1.5625 + t2 = 0.1875 + 1.5625

Reorder the terms:
1.5625 + -2.5t + t2 = 0.1875 + 1.5625

Combine like terms: 0.1875 + 1.5625 = 1.75
1.5625 + -2.5t + t2 = 1.75
