Let's understand the relationship between zeros and coefficients of a quadratic polynomial. If α and β are zeros of a quadratic polynomial, x2+bx+c=0 x 2 + b x + c = 0 , the sum of zeros is equal to the negative of b and the product of zeros is equal to the constant term c .

The standard form of a quadratic equation is ax² + bx + c=0, where ax² + bx + c where a,b and c are real numbers and a0. As, 'a' is the coefficient of x². It is known as the quadratic coefficient. 'b' is the coefficient of x. Hence, it is known as the linear coefficient .

In general, given the function, f(x), its zeros can be found by setting the function to zero. The values of x that represent the set equation are the zeroes of the function. To find the zeros of a function, find the values of x where f(x) = 0.
