4 the coefficient of the squared term: 

Divide each side by '4'.
0.25 + 14X + X2 = 0

Move the constant term to the right:

Add '-0.25' to each side of the equation.
0.25 + 14X + -0.25 + X2 = 0 + -0.25

Reorder the terms:
0.25 + -0.25 + 14X + X2 = 0 + -0.25

Combine like terms: 0.25 + -0.25 = 0.00
0.00 + 14X + X2 = 0 + -0.25
14X + X2 = 0 + -0.25

Combine like terms: 0 + -0.25 = -0.25
14X + X2 = -0.25

The X term is 14X.  Take half its coefficient (7).
