Which shows all the values of a that makes the rational expression 3a^2-27 /324-4a^2 unidentified

a = ± 9

Step-by-step explanation:

The denominator of the rational expression cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the values that a cannot be

324 - 4a² = 0 ( subtract 324 from both sides )

- 4a² = - 324 ( divide both sides by - 4 )

a² = 81 ( take the square root of both sides )

a = ± = ± 9 ← excluded values
