Answer:
[tex] \frac{ {x}^{2} - 1 }{ {x}^{2} - 25 } [/tex]
Step-by-step explanation:
[tex] \frac{x - 1}{x + 5} \times \frac{x + 1}{x - 5} [/tex]
To multiply the fraction, multiply the numerators and denominators separately
[tex] \frac{(x - 1) \times (x + 1)}{(x + 5) \times (x - 5)} [/tex]
Using [tex] {a}^{2} - {b}^{2} = (a - b)(a + b)[/tex] simplify the product
[tex] = \frac{ {x}^{2} - 1 }{ {x}^{2} - 25 } [/tex]
Hope this helps..
Best regards!!
