The sum of all solutions for x in the equation x^2 – 8x + 21 = |x – 2|+ 5 is equal to:	Choices:
A) –7
B) 7
C) 10
D) 12
E) 18
x^2 - 8x + 16 = |x-2|   RHS can be -ve or +ve   x^2 - 9x + 18 = 0   x^2 - 7x + 14 = 0   x= 7,6,3,2   We test all 3 values in original equation, all ok.   Thus, Sum = 7 + 6 +3 + 2=
