Can someone help me with this problem?

4 (9x² + 6xy + y²)

Step-by-step explanation:

Looking at the variables, the there is no common factor that applies for all three variables. But 36, 24, and 4 as a common factor, and the greatest is 4. 4 fits into 36, 24, and 4, so we can factor that out. Simply divide each terms by 4, then you will get:

4 (9x² + 6xy + y²)

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
