Factor completely
36x2 + 60x + 25
Factor completely
4n2 + 28n + 49

Find what values will multiply to give the last term and first term. Use those values to find what will add to give the middle term.
36 = 36*1 or 9*4 or 6*6
25 = 25*1 or 5*5
36x2 + 60x + 25 = (6x + 5)(6x + 5)
4n2 + 28n + 49 = (2n + 7)(2n + 7)
I hope this helps.
