4 + -6t + 15t2 = 0

Solving for variable 't'.

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

Divide each side by '15'.
0.2666666667 + -0.4t + t2 = 0

Move the constant term to the right:

Add '-0.2666666667' to each side of the equation.
0.2666666667 + -0.4t + -0.2666666667 + t2 = 0 + -0.2666666667

Reorder the terms:
0.2666666667 + -0.2666666667 + -0.4t + t2 = 0 + -0.2666666667

Combine like terms: 0.2666666667 + -0.2666666667 = 0.0000000000
0.0000000000 + -0.4t + t2 = 0 + -0.2666666667
-0.4t + t2 = 0 + -0.2666666667

Combine like terms: 0 + -0.2666666667 = -0.2666666667
-0.4t + t2 = -0.2666666667

The t term is -0.4t.  Take half its coefficient (-0.2).
Square it (0.04) and add it to both sides.

Add '0.04' to each side of the equation.
-0.4t + 0.04 + t2 = -0.2666666667 + 0.04

Reorder the terms:
0.04 + -0.4t + t2 = -0.2666666667 + 0.04

Combine like terms: -0.2666666667 + 0.04 = -0.2266666667
0.04 + -0.4t + t2 = -0.2266666667

Factor a perfect square on the left side:
(t + -0.2)(t + -0.2) = -0.2266666667

Can't calculate square root of the right side.

The solution to this equation could not be determined.
