perform the indicated operation and if possible simplify. (2x+4y)/(2x^2+5xy+2y^2)*(4x^2y^2)/(8x^28)÷(x^2+4xy+4y^2)/(x^26xy+9y^2)
i don't understand this the answer is (2xy)(x3y)^2/4(x1)(x+1)(x+2y)^2

Urgent math 
Reiny,
It factors to
2(x+2y)/((2x+1)(x+2)) * (2xy)(2x+y)/((8(x+1)(x1)) * (x3y)(x3y)/((+2y)(x+2y)) , I changed the division at the end to multiplication by "flipping" the fraction
= (2xy)(x3y)^2 / [ 4(x+1)(x1)(x+2y)^2 ]
= their answer
