0.6 + -7t + 5t2 = 0

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

Divide each side by '5'.
0.12 + -1.4t + t2 = 0

Move the constant term to the right:

Add '-0.12' to each side of the equation.
0.12 + -1.4t + -0.12 + t2 = 0 + -0.12

Reorder the terms:
0.12 + -0.12 + -1.4t + t2 = 0 + -0.12

Combine like terms: 0.12 + -0.12 = 0.00
0.00 + -1.4t + t2 = 0 + -0.12
-1.4t + t2 = 0 + -0.12

Combine like terms: 0 + -0.12 = -0.12
-1.4t + t2 = -0.12

The t term is -1.4t.  Take half its coefficient (-0.7).
Square it (0.49) and add it to both sides.

Add '0.49' to each side of the equation.
-1.4t + 0.49 + t2 = -0.12 + 0.49

Reorder the terms:
0.49 + -1.4t + t2 = -0.12 + 0.49

Combine like terms: -0.12 + 0.49 = 0.37
0.49 + -1.4t + t2 = 0.37

Factor a perfect square on the left side:
(t + -0.7)(t + -0.7) = 0.37
