Simplifying
0.5x + 3 = x2

Reorder the terms:
3 + 0.5x = x2

Solving
3 + 0.5x = x2

Solving for variable 'x'.

Combine like terms: x2 + -1x2 = 0
3 + 0.5x + -1x2 = 0

Begin completing the square.  Divide all terms by
-1 the coefficient of the squared term: 

Divide each side by '-1'.
-3 + -0.5x + x2 = 0

Move the constant term to the right:

Add '3' to each side of the equation.
-3 + -0.5x + 3 + x2 = 0 + 3

Reorder the terms:
-3 + 3 + -0.5x + x2 = 0 + 3

Combine like terms: -3 + 3 = 0
0 + -0.5x + x2 = 0 + 3
-0.5x + x2 = 0 + 3

Combine like terms: 0 + 3 = 3

The x term is -0.5x.  Take half its coefficient (-0.25).
Square it (0.0625) and add it to both sides.

Add '0.0625' to each side of the equation.
-0.5x + 0.0625 + x2 = 3 + 0.0625

Reorder the terms:
0.0625 + -0.5x + x2 = 3 + 0.0625

Combine like terms: 3 + 0.0625 = 3.0625
0.0625 + -0.5x + x2 = 3.0625

Factor a perfect square on the left side:
(x + -0.25)(x + -0.25) = 3.0625

Calculate the square root of the right side: 1.75

Break this problem into two subproblems by setting 
(x + -0.25) equal to 1.75 and -1.75.

Subproblem 1

x + -0.25 = 1.75 Simplifying x + -0.25 = 1.75 Reorder the terms: -0.25 + x = 1.75 Solving -0.25 + x = 1.75 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.25' to each side of the equation. -0.25 + 0.25 + x = 1.75 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + x = 1.75 + 0.25 x = 1.75 + 0.25 Combine like terms: 1.75 + 0.25 = 2 x = 2 Simplifying x = 2

Subproblem 2

x + -0.25 = -1.75 Simplifying x + -0.25 = -1.75 Reorder the terms: -0.25 + x = -1.75 Solving -0.25 + x = -1.75 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.25' to each side of the equation. -0.25 + 0.25 + x = -1.75 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + x = -1.75 + 0.25 x = -1.75 + 0.25 Combine like terms: -1.75 + 0.25 = -1.5 x = -1.5 Simplifying x = -1.5

Solution

The solution to the problem is based on the solutions from the subproblems. x = {2, -1.5}
