Question

What’s the value of x?

Answer 1

B and C

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 x cannot be.

solve

3x² - 75 = 0 ( add 75 to both sides )

3x² = 75 ( divide both sides by 3 )

x² = 25 ( take the square root of both sides )

x = ±
`√(25)` = ± 5 → B and C
