Answer:

a ≠ 2

Explanation:

Given


(a^2)/(-3a+6)

The denominator of the rational function cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the value that a cannot be, that is

- 3a + 6 = 0 ( subtract 6 from both sides )

- 3a = - 6 ( divide both sides by - 3 )

a = 2 ← excluded value
