Solving for variable 'x'.

Begin completing the square.

Move the constant term to the right:

Add '-140' to each side of the equation.
140 + 4x + -140 + x2 = 0 + -140

Reorder the terms:
140 + -140 + 4x + x2 = 0 + -140

Combine like terms: 140 + -140 = 0
0 + 4x + x2 = 0 + -140
4x + x2 = 0 + -140

Combine like terms: 0 + -140 = -140
4x + x2 = -140

The x term is 4x.  Take half its coefficient (2).
Square it (4) and add it to both sides.
