Begin completing the square.  Divide all terms by
-1 the coefficient of the squared term: 

Divide each side by '-1'.
-32 + -3x + x2 = 0

Move the constant term to the right:

Add '32' to each side of the equation.
-32 + -3x + 32 + x2 = 0 + 32

Reorder the terms:
-32 + 32 + -3x + x2 = 0 + 32

Combine like terms: -32 + 32 = 0
0 + -3x + x2 = 0 + 32
-3x + x2 = 0 + 32

Combine like terms: 0 + 32 = 32
-3x + x2 = 32

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 = 32 + 2.25

Reorder the terms:
2.25 + -3x + x2 = 32 + 2.25

Combine like terms: 32 + 2.25 = 34.25
2.25 + -3x + x2 = 34.25

Factor a perfect square on the left side:
(x + -1.5)(x + -1.5) = 34.25
