So a x +b =0

So a x = -b

So x = b/ a
NOTE :

1. The no of zero of a linear polynomial is 1 because its degree is 1.

2. The no of zero of a quadratic polynomial is 2 because its degree is 2.

3. The no of zero of a cubic polynomial is 3 because its degree is 3.

4. The no of zero of a nth polynomial is n because its degree is n.
NOTES:

1. The zero of a non -zero constant polynomial does not exist

Example: Zero of -5 is ________________

2. Zero of a zero polynomial are each and every real number.

3. For and real numbers value of zero polynomial = 0
