Consider the rational expressions x/(x-2) and x/(x-4).a)Evaluate each expression for x= 6. b)Evaluate each expression for x= 3.

Answer:a)  × / ( × - 2)  for × = 6     ⇒ 3/2     × / ( × - 4 )  for  ×= 6    ⇒ 3b)   × / ( × - 2)  for × = 3    ⇒ 3        × / ( × - 4 )  for  ×= 3   ⇒ -3      Step-by-step explanation:The expression:    × / ( × - 2)  for × = 6  ⇒  6/ ( 6 - 2) = 6/4 = 3/2The expression:    × / ( × - 4 )  for  ×= 6  ⇒  6/ (6 - 4) = 6/2 = 3The expression:    × / ( × - 2)  for × = 3  ⇒  3/ ( 3 - 2 ) = 3/1 = 3The expression:    × / ( × - 4 )  for  ×= 3  ⇒ 3/ ( 3 - 4 ) = 3/ (-1) =  -3
