Subproblem 1
Set the factor '(4 + 9x + -1x2)' equal to zero and attempt to solve:

Simplifying
4 + 9x + -1x2 = 0

Solving
4 + 9x + -1x2 = 0

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

Divide each side by '-1'.
-4 + -9x + x2 = 0

Move the constant term to the right:

Add '4' to each side of the equation.
