normally i would answer it as :
but with special products it would be:
(a^2)(x^2 ) + ( 2axy ) + ( y^2 )
does that mean
What do you mean by special product?
Yes. For any and , . Here and ; therefore, . You can check this by multiplying through explicitly, and also by substituting various numbers for a, x and y (e.g., a = x = y = 1).does that mean
