P(x)=x2-1;x=-2 find wheter the following zeroes of the pollynomials are indicated towsrds them​

Given:

The polynomial is:

To find:

Whether is a zero of the given polynomial or not.

Solution:

If is a zero of a polynomial, then .

We have,

Putting in the given polynomial.

Since , therefore is not a zero of the given polynomial.

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
