x2 - y2 + 9x - 9y =
(x2 + 9x) - (y2 + 9y) =
x(x + 9) - y(y + 9)
================================
Another way to go after it:
x2 - y2 + 9x - 9y =
(x2 - y2) + 9x - 9y =
(x + y) (x - y) + 9 (x - y) =
(x + y + 9) (x - y)
The following is the answer.
6x - 27xy= 3x(2 - 9y)=========
the answer is 9x-29y. if you need help with any kind of math visit www.AAAmath.com
3x-2y+9+9y-x = 2x+7y+9
7(5x + 9y)
y^2+9y-52 = (y+13)(y-4)
The slope is 0.
This statement is already nearly factored. The best we can do is pull out the 9 from each term:9x + 9y + 72 = 9(x + y + 8)
The following is the answer.
It can be simplified to: 9y-2x
-7x+9y = 54 9y = 7x+54 y = 7/9x+6 which is now in slope-intercept form
6xy+9y2
6x - 27xy= 3x(2 - 9y)=========
12
15y-15=0,y=1
Slope-intercept form is y = mx + b5x + 9y = -36Subtract 5x from each side:9y = -5x - 36Divide everything by 9:y = -5/9x - 4
(9y+2z)(y-3z)
