Find the quadratic polynominal whose zeroes are 2 and −6 . verify the relation between the coefficients and the zeroes of the polynomial.

  • 0

This is the basic and exam oriented question from polynomials in which we have zeroes of the quadratic polynomial and we have to find the quadratic polynomial and have to find the relation between the coefficients and the zeroes of the polynomial.

Kindly give me a detailed solution of this question

  1. Let α=2 and β=−6

    Sum of the zeroes = (α+β)=26=−4
    Product of the zeroes , αβ=2(−6)=−12

    Required quadratic polynomial is
    (α+β)x+αβ=(−4)x12
    =+4x12

    and
    sum of the zeroes =−4=−4/1=(coefficient of x)/(coefficient of )

    product of zeroes =−12×1=−12/1=constant term/coefficient of x²
