Question

Verify whether -2 is a zero of the polynomial x^2-x+6.

Answer 1

Answer:

put x=-2

x²-x+6

(-2)²-(-2)+6

4+2+6

12

therefore, no -2 is not a zero of given polynomial.

Answer 2

Answer:

The answer is NO

Step-by-step explanation:

x²-x+6

To verify that we should give 2 in the place of x.

(-2²)-(-2)+6

=4+2+6

=12

Since, we didn't get zero as the answer -2 is  not a zero of the polynomial.
