Here is an example:
9x^2  25y^2

3x  5y
Factor the numerator, its a difference of perfect squares.
9x^2  25y^2 = (3x  5y) (3x + 5y)
(3x  5y)(3x + 5y)
(3x)(3x) = 9x^2
(3x)(5y) = 15xy
(5y)(3x)= 15xy
(5y)(5y)= 25y^2
9x^2 + 15xy  15xy 25y^2
9x^2 25y^2 = (3x  5y)(3x + 5y)

9x^2  25y (3x  5y)(3x +5y)
 =  = 3x +5y
3x  5y 3x  5y
