Solving for variable 'y'.

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

Divide each side by '5'.
7 + -2.4y + y2 = 0

Move the constant term to the right:

Add '-7' to each side of the equation.
7 + -2.4y + -7 + y2 = 0 + -7

Reorder the terms:
7 + -7 + -2.4y + y2 = 0 + -7

Combine like terms: 7 + -7 = 0
0 + -2.4y + y2 = 0 + -7
-2.4y + y2 = 0 + -7

Combine like terms: 0 + -7 = -7
-2.4y + y2 = -7

The y term is -2.4y.  Take half its coefficient (-1.2).
Square it (1.44) and add it to both sides.

Add '1.44' to each side of the equation.
-2.4y + 1.44 + y2 = -7 + 1.44

Reorder the terms:
1.44 + -2.4y + y2 = -7 + 1.44

Combine like terms: -7 + 1.44 = -5.56
1.44 + -2.4y + y2 = -5.56

Factor a perfect square on the left side:
(y + -1.2)(y + -1.2) = -5.56

Can't calculate square root of the right side.
