Simplify the rational expression and state any excluded values 3x - 12 / x - 4

Answer 1

To simplify the rational expression 3x - 12 / x - 4, we can factor out the common factor in the numerator:

3(x - 4) / (x - 4)

Now we can cancel out the common factor (x - 4) from the numerator and the denominator:

3

Therefore, the simplified form of the rational expression is 3, and the excluded value is x = 4.
