Question

draw the graph of polynomial p(x)=x^2+2x-3 and find zeroes of it​

Answer 1

Answer:

zeros off the above polynomial are -1&3

First of all let try to understand what is a zero of a polynomial.

Zeroes of Polynomial are the real values of the variable for which the value of the polynomial becomes zero.

Let's try to draw the graph of the above given quadratic

Answer 2

Answer:

Zeroes of $p(x)=x^{2} +2x-3$ are $-3,1$.

Step-by-step explanation:

Given: $p(x)=x^{2} +2x-3$.

To draw graph & find zeroes.

Using graphing calculator the graph is shown below.

We know that zeroes of polynomial occur at the point where the graph crosses the x-axis.

By graph we can see that graph crosses the x-axis at $x=-3$ & $x=1$.

Hence zeroes of $p(x)=x^{2} +2x-3$ are $-3,1$.
