Answer 2

difference of two squares...

Answer 3

i need step by step work showen

Answer 4

hmmm i'll try but it's really a rule

a^2 - b^2 = (a+b)(a-b) is the property of the difference of two squares

your first monomial is 9x^2..this can be rewritten as (3x)^2 yes? therefore your a is 3x

your second monomial is 4y^2 rewritten is (2y)^2 so b=2y

substitute to the property..

(3x+2y)(3x-2y)
