from the graph.





​

Answer 1

I hopeit is helpful to u

sorry i didn't post graph in this

u plot the ordinates...

Answer 2

Answer: 3 and -1

Step-by-step explanation:

• Zero of the polynomial is that value of x for which the polynomial is equal to zero.
• Given, p(x)=$x^{2} -2x-3$
• So, $x^{2} -2x-3=0$

          ⇒ $x^{2} -3x+x-3=0$

          ⇒ x(x-3)+1(x-3)=0

          ⇒ (x-3)(x+1)=0

         ∴ x=3 and -1.

We get two values of x i.e., 3 and -1.

• Hence, the two zeroes of polynomial are 3 and -1.
