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

Divide each side by '-4'.
3.75 + -3.5x + x2 = 0

Move the constant term to the right:

Add '-3.75' to each side of the equation.
3.75 + -3.5x + -3.75 + x2 = 0 + -3.75

Reorder the terms:
3.75 + -3.75 + -3.5x + x2 = 0 + -3.75

Combine like terms: 3.75 + -3.75 = 0.00
0.00 + -3.5x + x2 = 0 + -3.75
-3.5x + x2 = 0 + -3.75

Combine like terms: 0 + -3.75 = -3.75
-3.5x + x2 = -3.75

The x term is -3.5x.  Take half its coefficient (-1.75).
Square it (3.0625) and add it to both sides.

Add '3.0625' to each side of the equation.
-3.5x + 3.0625 + x2 = -3.75 + 3.0625

Reorder the terms:
3.0625 + -3.5x + x2 = -3.75 + 3.0625

Combine like terms: -3.75 + 3.0625 = -0.6875
3.0625 + -3.5x + x2 = -0.6875

Factor a perfect square on the left side:
(x + -1.75)(x + -1.75) = -0.6875
