Question

Simplify the rational expression and find the excluded values.

x²-x / (x-1)(x+7)
Excluded values:

Answer 1

To simplify the rational expression x²-x / (x-1)(x+7), you can cancel out the common factor of x in the numerator and denominator. The excluded values are x = 1 and x = -7.

Step-by-step explanation:

To simplify the rational expression x²-x / (x-1)(x+7), you can cancel out the common factor of x in the numerator and denominator.

So, the simplified expression becomes (x(x-1)) / ((x-1)(x+7)).

The excluded values are the values of x that make the denominator equal to zero. In this case, the excluded values are x = 1 and x = -7.
