Question 1001306: 25x^2-36/5x+6

You can put this solution on YOUR website! 25x^2-36/5x+6
The numerator is all perfect squares, 25, x^2, and 36
it is a difference of squares and factors into
(5x+6)(5x-6)
divided by (5x+6), the second term cancels out
The answer is 5x-6
The rule for factoring difference of squares is to take the square root of each, and write it as two binomials, with the sign different.
49x^2-4y^2
7x-2y is the square root of everything.
(7x+2y)(7x-2y)
