What is the sum of all possible solutions to |x - 5|^2 + |x - 5| = 20 ?	Select:
A) -1	B) 6	C) 7	D) 10	E) 14
Denote |x - 5| as y: y^2 + y = 20 --&gt; y = -5 or y = 4. Discard the first solution since y = |x - 5|, so it's an absolute value and thus cannot be negative.   y = |x - 5| = 4 --&gt; x = 9 or x = -1. The sum =10   Answer: 10.
