If a(a + 2) = 120 and b(b + 2) = 120, where a ≠ b, then a + b =
Choose the correct choice from the following:	A) -4	B) -6	C) -2	D) -10	E) -8
i.e. if a = 10 then b = -12   or if a = -12 then b = 10   But in each case a+b = -12+10 = -2   Answer:-2
<result>C</result>
If a(a + 2) = 120 and b(b + 2) = 120, where a ≠ b, then a + b =
