Factor:
2x^(2)+ay-ax^(2)-2y

Use pythagorean’s theorem and find the missing side lengths of the two smaller triangles and add them together
13^2 - 12^2 = 5
15^2 - 12^2 = 9
5+9 = 14
14 is the length of each side of the square
14^2 + 14^2 = 19.8
19.8 is the diagonal length of the inside if the square

It'll be 14/21, 8/12, and 10/15.14/21=2/312/16=3/48/12=2/310/15=2/3
