Solving for variable 'x'.

Begin completing the square.

Move the constant term to the right:

Add '-10' to each side of the equation.
10 + 19x + -10 + x2 = 0 + -10

Reorder the terms:
10 + -10 + 19x + x2 = 0 + -10

Combine like terms: 10 + -10 = 0
0 + 19x + x2 = 0 + -10
19x + x2 = 0 + -10

Combine like terms: 0 + -10 = -10
19x + x2 = -10

The x term is 19x.  Take half its coefficient (9.5).
Square it (90.25) and add it to both sides.

Add '90.25' to each side of the equation.
19x + 90.25 + x2 = -10 + 90.25

Reorder the terms:
90.25 + 19x + x2 = -10 + 90.25

Combine like terms: -10 + 90.25 = 80.25
90.25 + 19x + x2 = 80.25

Factor a perfect square on the left side:
(x + 9.5)(x + 9.5) = 80.25

Calculate the square root of the right side: 8.958236434

Break this problem into two subproblems by setting 
(x + 9.5) equal to 8.958236434 and -8.958236434.

Subproblem 1
