Help pls!<br> Which rational function has zeros at x = -1 and x = 6 ?

bagirrra123 [75]

Answer:

$f(x) = \frac{x^{2} -5x-6}{x^{2} -4}$

Step-by-step explanation:

Let's factorize the 1st option :

⇒ $f(x) = \frac{x^{2} -5x-6}{x^{2} -4}$

⇒ $f(x) = \frac{x^{2}+x-6x-6 }{(x+2)(x-2)}$

⇒ $f(x) = \frac{(x+1)(x-6)}{(x+2)(x-2)}$

===============================================================

Finding the zeros :

⇒ Factors of numerator should be equated to 0

x + 1 = 0 ⇒ x = -1
x - 6 = 0 ⇒ x = 6

=============================================================

Solution :

$f(x) = \frac{x^{2} -5x-6}{x^{2} -4}$
