Solving for variable 'x'.

Begin completing the square.

Move the constant term to the right:

Add '-24' to each side of the equation.
24 + 54x + -24 + x2 = 0 + -24

Reorder the terms:
24 + -24 + 54x + x2 = 0 + -24

Combine like terms: 24 + -24 = 0
0 + 54x + x2 = 0 + -24
54x + x2 = 0 + -24

Combine like terms: 0 + -24 = -24
54x + x2 = -24

The x term is 54x.  Take half its coefficient (27).
Square it (729) and add it to both sides.

Add '729' to each side of the equation.
54x + 729 + x2 = -24 + 729

Reorder the terms:
729 + 54x + x2 = -24 + 729
