x²-9y² 2*(x+2y)²

------- * ---------------- =

2x+4y x+3y

Answer 1

x^2 - 9y^2          2(x+2y)^2       (x+3y)(x-3y)         2(x+2y)^2

--------------  *  ---------------  = ----------------- *  ---------------  =

   2x+4y               x+3y              2(x+2y)                x+y

   

= (x-3y)*(x+2y) = x^2 + 2xy -3xy - 6y^2 = x^2 -xy -6y^2
