If you are factoring 72:72=36x2=6x6x2=2x3x2x3x2so, it would be 2x2x2x3x3if you are looking for factors of 72:1,2,3,4,6,8,9,12,18,24,36,72The positive whole-number factors of 72 are:1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72.
66x^3 - 36x^2 = 6x^2(11x - 6) 55x - 30 = 5(11x - 6) 66x^3 - 36x^2 + 55x - 30 = (6x^2 + 5)(11x - 6)

(6x+5)(6x-5)
(6x + 5)(6x - 5)
It can be factored as 18(5-2x^2)
36x2 - 4y2 = (6x - 2y) (6x + 2y)
The difference of two squares is quick way to factor polynomials when certain constraints are met: Namely that you have two squares (e.g. 4, 25, 36x2 , 144a6) and one is subtracting from the others (e.g. 25 - 36x2). IF these two constraints are met, then you are able to factor the polynomial by finding the square roots of the squares. sqrt(25)=5 sqrt(36x2) = 6x Therefore 25 - 36x2 = (5+6x)(5-6x) in factored form. In general, given any two squares, a2 and b2, AND they are subtracting, a2 - b2, you can factor them to be (a + b)(a - b).
