2 times 3 times 3 times x times y = 18xy
We are missing an important sign (+/-) I shall assume 9x2 - 18xy + 9y2 9(x-y)(x-y)

The GCF for 16 24 18 is 2.
36y to the second power
GCF(18xy, 15xy) = 3xy LCM(18xy, 15xy) = 90xy
18xy is the GCF of 72x2y and 18xy
xy
The GCF is 6xy. The LCM is 72xy2
It appears to be 12y
63
It is -18xy
2 times 3 times 3 times x times y = 18xy
GCF = 9To find the LCM, find the prime factorization of each number9y = 3 * 3 * y18x = 2 * 3 * 3 * xLCM = 2 * 3 * 3 * x * y = 18xy
36y^2 - 1 = (6y - 1)(6y + 1)
