4t^2-8t+25=0

Solution for 4t^2-8t+25=0 equation:

Simplifying
4t2 + -8t + 25 = 0

Reorder the terms:
25 + -8t + 4t2 = 0

Solving
25 + -8t + 4t2 = 0

Solving for variable 't'.

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

Divide each side by '4'.
6.25 + -2t + t2 = 0

Move the constant term to the right:

Add '-6.25' to each side of the equation.
6.25 + -2t + -6.25 + t2 = 0 + -6.25

Reorder the terms:
6.25 + -6.25 + -2t + t2 = 0 + -6.25

Combine like terms: 6.25 + -6.25 = 0.00
0.00 + -2t + t2 = 0 + -6.25
-2t + t2 = 0 + -6.25

Combine like terms: 0 + -6.25 = -6.25
-2t + t2 = -6.25

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 = -6.25 + 1

Reorder the terms:
1 + -2t + t2 = -6.25 + 1

Combine like terms: -6.25 + 1 = -5.25
1 + -2t + t2 = -5.25

Factor a perfect square on the left side:
(t + -1)(t + -1) = -5.25

Can't calculate square root of the right side.

The solution to this equation could not be determined.
