What you need to do is add the two equations and combine like terms to get h(x). Refer to the photo for a better explanation.
The answer would simplify to 1/6.
Answer:
Step-by-step explanation:
x² - x -6 = x² + 2x - 3x - 3*2
=x(x + 2) - 3(x + 2)
= (x + 2 )(x - 3)


The formula of combination is

We have

and
