Let us consider a polynomial p(x) = 2x – 5. Its graph can be drawn as follows:

If we notice the above graph carefully, then we can see that the graph of the polynomial p(x) = 2x – 5 passes through the x-axis at a point.

Do you know what is the value of the polynomial p(x) at the x-coordinate of this point?

Let us find out how.

Thus,
