Question

Relationships between zeroes and coefficient of polynomial .

Answer 1

$\alpha + \beta = - b \div a$
$\alpha \times \beta = c \div a$

Answer 2

"Relationship between zeros and coefficients of a quadratic polynomial" is the stuff which is much required to the students who study high school math .

To understand "relationship between zeros and coefficients of a quadratic polynomial",  let us consider the quadratic polynomial. 

 P(x) = ax² + bx + c

(Here a, b and c are real and rational numbers)

Let "α" and "β" be the two zeros of the above quadratic polynomial

The basic relationships between the zeros and the coefficients of 

 P(x) = ax² + bx + c are
