Answer 1

Answer:

There are always two zeros for any quadratic polynomial. The zeros of a polynomial are those values of the variable for which the polynomial as a whole has zero value. The sum and product of zeros in a quadratic polynomial have a direct relation with the coefficients of variables in the polynomial. Then it becomes very easy to calculate the sum and product of zeros even without knowing the values of zeros of a polynomial. Let's learn about it in detail
