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

Divide each side by '0.05'.
1.4 + -6x + x2 = 0

Move the constant term to the right:

Add '-1.4' to each side of the equation.
1.4 + -6x + -1.4 + x2 = 0 + -1.4

Reorder the terms:
1.4 + -1.4 + -6x + x2 = 0 + -1.4

Combine like terms: 1.4 + -1.4 = 0.0
0.0 + -6x + x2 = 0 + -1.4
-6x + x2 = 0 + -1.4

Combine like terms: 0 + -1.4 = -1.4
