If a(a + 2) = 80 and b(b + 2) = 80, where a ≠ b, then a + b =
Choose the correct choice from the following answers:	A) -3	B) -4	C) -6	D) -8	E) -2
i.e. if a = 8 then b = -10   or if a = -10 then b = 8   But in each case a+b = -10+8 = -2   Answer:-2
<result>E</result>
If a(a + 2) = 80 and b(b + 2) = 80, where a ≠ b, then a + b =
