To simplify the sum, first we need to combine like terms in the numerator:
x - 2x + 3 + 10x = (1-2+10)x + 3 = 9x + 3
Now, let's simplify the denominator using the difference of squares formula:
x^2 - 9 = (x+3)(x-3)
So, the simplified expression is:
(9x + 3)/(x+3)(x-3)
There are no restrictions on the variables in this case.
