The product of 4xy and y² + 2x can also be written as
4xy(y² + 2x)
When we have brackets like this, we multiply whatever is left of the brackets by everything inside.
1) 4xy multiplied by y²
    4xy x y² = 4xy³
2) 4xy multiplied by 2x
    4xy x 2x = 8x²y
3) Add together 4xy³ and 8x²y 
    4xy³ + 8x²y
        
             
        
        
        
That is 2015! or 2015 factorial
that is big
not sure if a joke but the answer is (see attachment)
