0.1t^2-0.2t+3=0

Solution for 0.1t^2-0.2t+3=0 equation:

Simplifying
0.1t2 + -0.2t + 3 = 0

Reorder the terms:
3 + -0.2t + 0.1t2 = 0

Solving
3 + -0.2t + 0.1t2 = 0

Solving for variable 't'.

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

Divide each side by '0.1'.
30 + -2t + t2 = 0

Move the constant term to the right:

Add '-30' to each side of the equation.
30 + -2t + -30 + t2 = 0 + -30

Reorder the terms:
30 + -30 + -2t + t2 = 0 + -30

Combine like terms: 30 + -30 = 0
0 + -2t + t2 = 0 + -30
-2t + t2 = 0 + -30

Combine like terms: 0 + -30 = -30
-2t + t2 = -30

The t term is -2t.  Take half its coefficient (-1).
Square it (1) and add it to both sides.

Add '1' to each side of the equation.
-2t + 1 + t2 = -30 + 1

Reorder the terms:
1 + -2t + t2 = -30 + 1

Combine like terms: -30 + 1 = -29
1 + -2t + t2 = -29

Factor a perfect square on the left side:
(t + -1)(t + -1) = -29

Can't calculate square root of the right side.

The solution to this equation could not be determined.
