Divide each side by '4'.
4.25 + 1.75n + n2 = 0

Move the constant term to the right:

Add '-4.25' to each side of the equation.
4.25 + 1.75n + -4.25 + n2 = 0 + -4.25

Reorder the terms:
4.25 + -4.25 + 1.75n + n2 = 0 + -4.25

Combine like terms: 4.25 + -4.25 = 0.00
0.00 + 1.75n + n2 = 0 + -4.25
1.75n + n2 = 0 + -4.25

Combine like terms: 0 + -4.25 = -4.25
1.75n + n2 = -4.25
