Question

find the quadratic polynomial whose zeros are 3 and minus 4 respectively

Answer 1

let zeroes are alpha(3) and beta(-4)
alpha+beta =3+(-4)
=3-4=-1
alpha×beta =3×(-4)
=-12
so,as we know that the quadratic equation is
k{x square-(alpha+beta)+(alpha×beta)} is equation me alpha+beta or alpha×beta ki value put Kar do answer aa jaega
