Solving for variable 'x'.

Reorder the terms:
82 + 14x + x2 = -14x + 14x + -1x2 + x2

Combine like terms: -14x + 14x = 0
82 + 14x + x2 = 0 + -1x2 + x2
82 + 14x + x2 = -1x2 + x2

Combine like terms: -1x2 + x2 = 0
82 + 14x + x2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-82' to each side of the equation.
82 + 14x + -82 + x2 = 0 + -82

Reorder the terms:
82 + -82 + 14x + x2 = 0 + -82

Combine like terms: 82 + -82 = 0
0 + 14x + x2 = 0 + -82
14x + x2 = 0 + -82

Combine like terms: 0 + -82 = -82
14x + x2 = -82

The x term is 14x.  Take half its coefficient (7).
Square it (49) and add it to both sides.

Add '49' to each side of the equation.
14x + 49 + x2 = -82 + 49

Reorder the terms:
49 + 14x + x2 = -82 + 49

Combine like terms: -82 + 49 = -33
49 + 14x + x2 = -33

Factor a perfect square on the left side:
(x + 7)(x + 7) = -33

Can't calculate square root of the right side.
