Solving for variable 't'.

Begin completing the square.

Move the constant term to the right:

Add '-40' to each side of the equation.
40 + 3t + -40 + t2 = 0 + -40

Reorder the terms:
40 + -40 + 3t + t2 = 0 + -40

Combine like terms: 40 + -40 = 0
0 + 3t + t2 = 0 + -40
3t + t2 = 0 + -40

Combine like terms: 0 + -40 = -40
3t + t2 = -40

The t term is 3t.  Take half its coefficient (1.5).
Square it (2.25) and add it to both sides.

Add '2.25' to each side of the equation.
3t + 2.25 + t2 = -40 + 2.25

Reorder the terms:
2.25 + 3t + t2 = -40 + 2.25

Combine like terms: -40 + 2.25 = -37.75
2.25 + 3t + t2 = -37.75

Factor a perfect square on the left side:
(t + 1.5)(t + 1.5) = -37.75
