That's what I got. to rationalize the numerator you have to multiply by the conjugate, in this case (√3 + 9) / (√3 + 9), which is what it looks like you did.

Step-by-step explanation:
Completing the square:
x^2 + 10x - 13 = x^2 + 10x + 25 - 25 - 13 = (x + 5)^2 - 38
Part A:
25 - 25
Part B:
(x + 5)^2 - 38
5x + 4x + 6x = 15x
3y - 5y + 6y - 12y = -8y
6 + 12 - 8 = 10
15x - 8y + 10
