One number is two more than another. The difference between their squares is 60. What are the numbers?
So far I've written out this: (x+2)^2-(x)^2=60
I've tried expanding it any way i possibly can and I've always come up with the wrong answer after this. Our book didn't give us any examples about how to expand a word problem with the DIFFERENCE of something, only the SUM. So I really really hope I can get some help!
