6XY/3X
you have the right to cancel any numerator with any denominator. The 3 goes evenly into 6 and the x goes into x
2y
is the simplest form
Since there are no common factors, just multiply everything: 3x times 2y = 6xy
If 2 divided by 3x it is equal to 2/3x
6x2+6xy-3x
The GCF is 3xy.
3x(2y + 1)
xy(7+2y-3x)-6xy
(3x - y)(3x - y)
9x^2-6xy+y^2 = (y-3x)^2 (y-3x)^2-81 -> ((y-3x)+9)((y-3x)-9)
6xy
(3x - y)(3x - y) - 81
9x2 - 6xy + y2 - 81 = (3x - y)2 - 92 = (3x - y - 9)(3x - y + 9)
9x2 - 6xy + y2 - 81 = (3x - y)2 - 81 = (3x - y - 9)*(3x - y + 9)
