5 the coefficient of the squared term: 

Divide each side by '5'.
2.6 + -1.6x + x2 = 0

Move the constant term to the right:

Add '-2.6' to each side of the equation.
2.6 + -1.6x + -2.6 + x2 = 0 + -2.6

Reorder the terms:
2.6 + -2.6 + -1.6x + x2 = 0 + -2.6

Combine like terms: 2.6 + -2.6 = 0.0
0.0 + -1.6x + x2 = 0 + -2.6
-1.6x + x2 = 0 + -2.6
