Combine like terms: 1.3 + -1.3 = 0.0
0.2 + -3t + 16t2 = 0.0 + 3t + -3t + -16t2 + 16t2
0.2 + -3t + 16t2 = 3t + -3t + -16t2 + 16t2

Combine like terms: 3t + -3t = 0
0.2 + -3t + 16t2 = 0 + -16t2 + 16t2
0.2 + -3t + 16t2 = -16t2 + 16t2

Combine like terms: -16t2 + 16t2 = 0
0.2 + -3t + 16t2 = 0

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

Divide each side by '16'.
0.0125 + -0.1875t + t2 = 0

Move the constant term to the right:

Add '-0.0125' to each side of the equation.
0.0125 + -0.1875t + -0.0125 + t2 = 0 + -0.0125

Reorder the terms:
0.0125 + -0.0125 + -0.1875t + t2 = 0 + -0.0125

Combine like terms: 0.0125 + -0.0125 = 0.0000
0.0000 + -0.1875t + t2 = 0 + -0.0125
-0.1875t + t2 = 0 + -0.0125

Combine like terms: 0 + -0.0125 = -0.0125
-0.1875t + t2 = -0.0125

The t term is -0.1875t.  Take half its coefficient (-0.09375).
Square it (0.0087890625) and add it to both sides.

Add '0.0087890625' to each side of the equation.
-0.1875t + 0.0087890625 + t2 = -0.0125 + 0.0087890625

Reorder the terms:
0.0087890625 + -0.1875t + t2 = -0.0125 + 0.0087890625

Combine like terms: -0.0125 + 0.0087890625 = -0.0037109375
0.0087890625 + -0.1875t + t2 = -0.0037109375

Factor a perfect square on the left side:
(t + -0.09375)(t + -0.09375) = -0.0037109375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
