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

Divide each side by '4'.
1.75 + -0.75n + n2 = 0

Move the constant term to the right:

Add '-1.75' to each side of the equation.
1.75 + -0.75n + -1.75 + n2 = 0 + -1.75

Reorder the terms:
1.75 + -1.75 + -0.75n + n2 = 0 + -1.75

Combine like terms: 1.75 + -1.75 = 0.00
0.00 + -0.75n + n2 = 0 + -1.75
-0.75n + n2 = 0 + -1.75

Combine like terms: 0 + -1.75 = -1.75
-0.75n + n2 = -1.75

The n term is -0.75n.  Take half its coefficient (-0.375).
Square it (0.140625) and add it to both sides.

Add '0.140625' to each side of the equation.
-0.75n + 0.140625 + n2 = -1.75 + 0.140625

Reorder the terms:
0.140625 + -0.75n + n2 = -1.75 + 0.140625

Combine like terms: -1.75 + 0.140625 = -1.609375
0.140625 + -0.75n + n2 = -1.609375

Factor a perfect square on the left side:
(n + -0.375)(n + -0.375) = -1.609375

Can't calculate square root of the right side.
