It is -18xy
y(x - 9)(x - 9)
0.3333
2y(x - 5)(x^2 + 9)
√18xy = √(9*2xy) = √9*√2xy = 3*√(2xy)
It is -18xy
GCF(18xy, 15xy) = 3xy LCM(18xy, 15xy) = 90xy
2 times 3 times 3 times x times y = 18xy
72xy
lcm(8x, 18xy) = 72xy 8x = 23 x x 18xy = 2 x 32 x x x y lcm = 23 x 32 x x x y= 72xy
the GCF is 6y
xy
We are missing an important sign (+/-) I shall assume 9x2 - 18xy + 9y2 9(x-y)(x-y)
63
-12
18xy is the GCF of 72x2y and 18xy
lcm(8x, 18xy) = 72xy
