Question

please help me it's urgent ​

Answer 1

Answer:

1. a) binomial

  b) a=2a, b=3b

     = 2a * 3b

     = 6ab

c) 12

2. a) = p-q-p-q

       = -2q

b) = x+2+x-2

   = 2x

3. a) = 2x^2 - 3y^2 + 9x^2 + 6y^2 + (-3x^2 - 5y^2)

       = 2x^2 - 3y^2 + 9x^2 +6y^2 - 3x^2 - 5y^2

       = 8x^2 - 2y^2

b) = a^2 + b^2 - 2ab - (a^2 + b^2 + 2ab)

   = a^2 + b^2 - 2ab - a^2 - b^2 - 2ab

   = -4ab

c) = 2x^2 + 4xy + 5 - xy - y^2

   = 2x^2 + 3xy - y^2 + 5
