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

Divide each side by '-5'.
2.46 + -0.44x + x2 = 0

Move the constant term to the right:

Add '-2.46' to each side of the equation.
2.46 + -0.44x + -2.46 + x2 = 0 + -2.46

Reorder the terms:
2.46 + -2.46 + -0.44x + x2 = 0 + -2.46

Combine like terms: 2.46 + -2.46 = 0.00
0.00 + -0.44x + x2 = 0 + -2.46
-0.44x + x2 = 0 + -2.46

Combine like terms: 0 + -2.46 = -2.46
-0.44x + x2 = -2.46

The x term is -0.44x.  Take half its coefficient (-0.22).
Square it (0.0484) and add it to both sides.

Add '0.0484' to each side of the equation.
-0.44x + 0.0484 + x2 = -2.46 + 0.0484

Reorder the terms:
0.0484 + -0.44x + x2 = -2.46 + 0.0484

Combine like terms: -2.46 + 0.0484 = -2.4116
0.0484 + -0.44x + x2 = -2.4116

Factor a perfect square on the left side:
(x + -0.22)(x + -0.22) = -2.4116

Can't calculate square root of the right side.

The solution to this equation could not be determined.
