Answer by Fermat(136)   (Show Source):
You can put this solution on YOUR website! I'm not too sure if this is what you want, but...
The difference of two squares.
==============================
a² - b² = (a+b)(a-b)
Applying that to the polynomial (actually it's a binomial!)
49y² - 64 = (7y)² - (8)²
(7y)² - (8)² = (7y-8)(7y+8)
49y² - 64 = (7y-8)(7y+8)
========================
If this helps, good. If not, then can you just post your question again?
