Multiplication and division of integers Three monomials are given: A & sup2;, B & sup2;, 2Ab 1. Choose any two of the above three monomials and factorize them 2. When a = 2010, B = 2009, the value of ball a & sup2; + B & sup2; - 2Ab
a²-b²
=(a+b)(a-b)
b²-2ab=b(a-2a)
a²-2ab
=a(a-2b)
a²+b²-2ab
=(a+b)^2-2ab-2ab
=(a+b)^2-4ab
=4019^2-4*2010*2009
=1
