1. Answer:

   7x⁴y³-14x²y⁴

   Step-by-step explanation:

   =7xy(x³y²-2xy³)

   =7x⁴y³-14x²y⁴

   if x= 1 and y=2

   LHS

   7xy(x³y²-2xy³)

   =7(1)(2)[1³(2)²-2(1)(2)³]

   =14[4-16]

   =14(-12)

   =-168

   RHS

   =7x⁴y³-14x²y⁴

   =7(1)⁴(2)³-14(1)²(2⁴)

   =7(8)-14(16)

   =56-224

   =-168

   LHS= RHS

   hence verified.
