Factorise by splitting the middle term:
x^2120xy625y^2

math 
PsyDAG
625 factors into 5 * 5 * 5 * 5. You have to combine the above factors, so the difference will equal 120.
5 * 5 * 5 = 125
125  5 = 120, or even better 5  125 = 120
Therefore x^2120xy625y^2 = (x+5y)(x125y)
Although this may not be the process you were seeking, I hope this helps. Thanks for asking.
