Answer 2

To solve the equation $\frac{{x^2 - 9x - 10}}{{x^2 - 1}} = 0$, you'll want to find the values of $x$ that make the expression equal to zero. First, factor both the numerator and the denominator:

$\frac{{(x - 10)(x + 1)}}{{(x - 1)(x + 1)}} = 0$

Now, you can see that the denominator has a factor of $(x + 1)$. To solve for $x$, set each factor in the numerator equal to zero and solve for $x$:

1. $x - 10 = 0$ $x = 10$

2. $x + 1 = 0$ $x = -1$

So, the solutions for the equation are $x = 10$ and $x = -1$. These are the values of $x$ that make the expression $\frac{{x^2 - 9x - 10}}{{x^2 - 1}}$ equal to zero.
