You can put this solution on YOUR website! My pleasure :)
Okay so first we need to determine what coefficients or variables are in common in the expression. Our coefficients are 5, 20, 1 and 4 and we need to find a greatest common factor (GCF)of these four numbers. The greatest common factor of the coefficients is 1, so we cannot pull out a coefficient from our expression. Now we need to look at the variables to see what they have in common. Our variables are x^2, x , xy and y. And...they have nothing in common!?!
This expression cannot be factored any further. :( Let me know if you have any more questions. ;)
