2.25 + -3t + t2 = 0.00

Begin completing the square.

Move the constant term to the right:

Add '-2.25' to each side of the equation.
2.25 + -3t + -2.25 + t2 = 0.00 + -2.25

Reorder the terms:
2.25 + -2.25 + -3t + t2 = 0.00 + -2.25

Combine like terms: 2.25 + -2.25 = 0.00
0.00 + -3t + t2 = 0.00 + -2.25
-3t + t2 = 0.00 + -2.25

Combine like terms: 0.00 + -2.25 = -2.25
-3t + t2 = -2.25

The t term is -3t.  Take half its coefficient (-1.5).
Square it (2.25) and add it to both sides.

Add '2.25' to each side of the equation.
-3t + 2.25 + t2 = -2.25 + 2.25

Reorder the terms:
2.25 + -3t + t2 = -2.25 + 2.25

Combine like terms: -2.25 + 2.25 = 0.00
2.25 + -3t + t2 = 0.00

Factor a perfect square on the left side:
(t + -1.5)(t + -1.5) = 0.00

Calculate the square root of the right side: 0.00

Break this problem into two subproblems by setting 
(t + -1.5) equal to 0.00 and 0.00.

Subproblem 1

t + -1.5 = 0.00 Simplifying t + -1.5 = 0.00 Reorder the terms: -1.5 + t = 0.00 Solving -1.5 + t = 0.00 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + t = 0.00 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + t = 0.00 + 1.5 t = 0.00 + 1.5 Combine like terms: 0.00 + 1.5 = 1.5 t = 1.5 Simplifying t = 1.5

Subproblem 2

t + -1.5 = 0.00 Simplifying t + -1.5 = 0.00 Reorder the terms: -1.5 + t = 0.00 Solving -1.5 + t = 0.00 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + t = 0.00 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + t = 0.00 + 1.5 t = 0.00 + 1.5 Combine like terms: 0.00 + 1.5 = 1.5 t = 1.5 Simplifying t = 1.5

Solution

The solution to the problem is based on the solutions from the subproblems. t = {1.5, 1.5}
