Subproblem 2
Set the factor '(1 + 18bc)' equal to zero and attempt to solve:

Simplifying
1 + 18bc = 0

Solving
1 + 18bc = 0

Move all terms containing a to the left, all other terms to the right.

Add '-1' to each side of the equation.
1 + -1 + 18bc = 0 + -1

Combine like terms: 1 + -1 = 0
0 + 18bc = 0 + -1
18bc = 0 + -1

Combine like terms: 0 + -1 = -1
18bc = -1

Add '-18bc' to each side of the equation.
18bc + -18bc = -1 + -18bc

Combine like terms: 18bc + -18bc = 0
0 = -1 + -18bc

Simplifying
0 = -1 + -18bc
