Solving for variable 't'.

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

Divide each side by '10'.
0.9 + t + t2 = 0

Move the constant term to the right:

Add '-0.9' to each side of the equation.
0.9 + t + -0.9 + t2 = 0 + -0.9

Reorder the terms:
0.9 + -0.9 + t + t2 = 0 + -0.9

Combine like terms: 0.9 + -0.9 = 0.0
0.0 + t + t2 = 0 + -0.9
t + t2 = 0 + -0.9

Combine like terms: 0 + -0.9 = -0.9
t + t2 = -0.9

The t term is t.  Take half its coefficient (0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
 + 0.25 + t2 = -0.9 + 0.25

Combine like terms:  + 0.25 = 1.25
1.25 + t2 = -0.9 + 0.25

Combine like terms: -0.9 + 0.25 = -0.65
1.25 + t2 = -0.65

Factor a perfect square on the left side:
(t + 0.5)(t + 0.5) = -0.65

Can't calculate square root of the right side.

The solution to this equation could not be determined.
