Solving
-22 + 1.5t + t2 = 0

Solving for variable 't'.

Begin completing the square.

Move the constant term to the right:

Add '22' to each side of the equation.
-22 + 1.5t + 22 + t2 = 0 + 22

Reorder the terms:
-22 + 22 + 1.5t + t2 = 0 + 22

Combine like terms: -22 + 22 = 0
0 + 1.5t + t2 = 0 + 22
1.5t + t2 = 0 + 22

Combine like terms: 0 + 22 = 22
1.5t + t2 = 22

The t term is 1.5t.  Take half its coefficient (0.75).
Square it (0.5625) and add it to both sides.

Add '0.5625' to each side of the equation.
1.5t + 0.5625 + t2 = 22 + 0.5625

Reorder the terms:
0.5625 + 1.5t + t2 = 22 + 0.5625

Combine like terms: 22 + 0.5625 = 22.5625
0.5625 + 1.5t + t2 = 22.5625

Factor a perfect square on the left side:
(t + 0.75)(t + 0.75) = 22.5625

Calculate the square root of the right side: 4.75

Break this problem into two subproblems by setting 
(t + 0.75) equal to 4.75 and -4.75.

Subproblem 1

t + 0.75 = 4.75 Simplifying t + 0.75 = 4.75 Reorder the terms: 0.75 + t = 4.75 Solving 0.75 + t = 4.75 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '-0.75' to each side of the equation. 0.75 + -0.75 + t = 4.75 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + t = 4.75 + -0.75 t = 4.75 + -0.75 Combine like terms: 4.75 + -0.75 = 4 t = 4 Simplifying t = 4

Subproblem 2

t + 0.75 = -4.75 Simplifying t + 0.75 = -4.75 Reorder the terms: 0.75 + t = -4.75 Solving 0.75 + t = -4.75 Solving for variable 't'. Move all terms containing t to the left, all other terms to the right. Add '-0.75' to each side of the equation. 0.75 + -0.75 + t = -4.75 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + t = -4.75 + -0.75 t = -4.75 + -0.75 Combine like terms: -4.75 + -0.75 = -5.5 t = -5.5 Simplifying t = -5.5

Solution

The solution to the problem is based on the solutions from the subproblems. t = {4, -5.5}
