3-5t+t^2=0

Solution for 3-5t+t^2=0 equation:

Simplifying
3 + -5t + t2 = 0

Solving
3 + -5t + t2 = 0

Solving for variable 't'.

Begin completing the square.

Move the constant term to the right:

Add '-3' to each side of the equation.
3 + -5t + -3 + t2 = 0 + -3

Reorder the terms:
3 + -3 + -5t + t2 = 0 + -3

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

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

The t term is -5t.  Take half its coefficient (-2.5).
Square it (6.25) and add it to both sides.

Add '6.25' to each side of the equation.
-5t + 6.25 + t2 = -3 + 6.25

Reorder the terms:
6.25 + -5t + t2 = -3 + 6.25

Combine like terms: -3 + 6.25 = 3.25
6.25 + -5t + t2 = 3.25

Factor a perfect square on the left side:
(t + -2.5)(t + -2.5) = 3.25

Calculate the square root of the right side: 1.802775638

Break this problem into two subproblems by setting 
(t + -2.5) equal to 1.802775638 and -1.802775638.

Subproblem 1
t + -2.5 = 1.802775638

Simplifying
t + -2.5 = 1.802775638

-2.5 + t = 1.802775638

Solving
-2.5 + t = 1.802775638

Solving for variable 't'.

Move all terms containing t to the left, all other terms to the right.

Add '2.5' to each side of the equation.
-2.5 + 2.5 + t = 1.802775638 + 2.5

Combine like terms: -2.5 + 2.5 = 0.0
0.0 + t = 1.802775638 + 2.5
t = 1.802775638 + 2.5

Combine like terms: 1.802775638 + 2.5 = 4.302775638
t = 4.302775638

Simplifying
t = 4.302775638

Subproblem 2
t + -2.5 = -1.802775638

Simplifying
t + -2.5 = -1.802775638

Reorder the terms:
-2.5 + t = -1.802775638

Solving
-2.5 + t = -1.802775638

Solving for variable 't'.

Move all terms containing t to the left, all other terms to the right.

Add '2.5' to each side of the equation.
-2.5 + 2.5 + t = -1.802775638 + 2.5

Combine like terms: -2.5 + 2.5 = 0.0
0.0 + t = -1.802775638 + 2.5
t = -1.802775638 + 2.5

Combine like terms: -1.802775638 + 2.5 = 0.697224362
t = 0.697224362

Simplifying
t = 0.697224362
