Solution for 0.5=3t-5t^2 equation:


Simplifying
0.5 = 3t + -5t2

Solving
0.5 = 3t + -5t2

Solving for variable 't'.

Reorder the terms:
0.5 + -3t + 5t2 = 3t + -3t + -5t2 + 5t2

Combine like terms: 3t + -3t = 0
0.5 + -3t + 5t2 = 0 + -5t2 + 5t2
0.5 + -3t + 5t2 = -5t2 + 5t2

Combine like terms: -5t2 + 5t2 = 0
0.5 + -3t + 5t2 = 0

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

Divide each side by '5'.
0.1 + -0.6t + t2 = 0

Move the constant term to the right:

Add '-0.1' to each side of the equation.
0.1 + -0.6t + -0.1 + t2 = 0 + -0.1

Reorder the terms:
0.1 + -0.1 + -0.6t + t2 = 0 + -0.1

Combine like terms: 0.1 + -0.1 = 0.0
0.0 + -0.6t + t2 = 0 + -0.1
-0.6t + t2 = 0 + -0.1

Combine like terms: 0 + -0.1 = -0.1
-0.6t + t2 = -0.1

The t term is -0.6t.  Take half its coefficient (-0.3).
Square it (0.09) and add it to both sides.

Add '0.09' to each side of the equation.
-0.6t + 0.09 + t2 = -0.1 + 0.09

Reorder the terms:
0.09 + -0.6t + t2 = -0.1 + 0.09

Combine like terms: -0.1 + 0.09 = -0.01
0.09 + -0.6t + t2 = -0.01

Factor a perfect square on the left side:
(t + -0.3)(t + -0.3) = -0.01

Can't calculate square root of the right side.

The solution to this equation could not be determined.
