To factor a perfect square, it should be in the form a2+2ab+b2 For example: 9x2+18xy+9y2 First factor out the 9: 9(x2+2xy+y2) Make a2+2ab+b2 into (a+b)2 : 9(x+y)2
a proper factor is a factor.

18xy is the GCF of 72x2y and 18xy
y(x - 9)(x - 9)
It is -18xy
2y(x - 5)(x^2 + 9)
To find the least common multiple (LCM) of 8x and 18xy, we need to identify the highest power of each prime factor that appears in either number. The prime factors of 8x are 2 and x, while the prime factors of 18xy are 2, 3, x, and y. The LCM is the product of the highest power of each prime factor: 2^3 * 3^1 * x^1 * y^1 = 24xy. Therefore, the LCM for 8x and 18xy is 24xy.
GCF(18xy, 15xy) = 3xy LCM(18xy, 15xy) = 90xy
(3x - y)(3x - 5y) and (2x + 1)(2x + 11)
72xy
the GCF is 6y
