Combine like terms: 1.4 + -1.4 = 0.0
-1.4 + 1.5x + -0.5x2 = 0.0 + -1.5x + 1.5x + 0.5x2 + -0.5x2
-1.4 + 1.5x + -0.5x2 = -1.5x + 1.5x + 0.5x2 + -0.5x2

Combine like terms: -1.5x + 1.5x = 0.0
-1.4 + 1.5x + -0.5x2 = 0.0 + 0.5x2 + -0.5x2
-1.4 + 1.5x + -0.5x2 = 0.5x2 + -0.5x2

Combine like terms: 0.5x2 + -0.5x2 = 0.0
-1.4 + 1.5x + -0.5x2 = 0.0

Begin completing the square.  Divide all terms by
-0.5 the coefficient of the squared term: 

Divide each side by '-0.5'.
2.8 + -3x + x2 = 0

Move the constant term to the right:

Add '-2.8' to each side of the equation.
2.8 + -3x + -2.8 + x2 = 0 + -2.8

Reorder the terms:
2.8 + -2.8 + -3x + x2 = 0 + -2.8

Combine like terms: 2.8 + -2.8 = 0.0
0.0 + -3x + x2 = 0 + -2.8
-3x + x2 = 0 + -2.8

Combine like terms: 0 + -2.8 = -2.8
-3x + x2 = -2.8

The x term is -3x.  Take half its coefficient (-1.5).
Square it (2.25) and add it to both sides.

Add '2.25' to each side of the equation.
-3x + 2.25 + x2 = -2.8 + 2.25

Reorder the terms:
2.25 + -3x + x2 = -2.8 + 2.25

Combine like terms: -2.8 + 2.25 = -0.55
2.25 + -3x + x2 = -0.55

Factor a perfect square on the left side:
(x + -1.5)(x + -1.5) = -0.55

Can't calculate square root of the right side.

The solution to this equation could not be determined.
