Question

Sum of zeros of a quadratic polynomial k y + 2 y + 3 k is equal to twice of the product find the value of k

Answer 1

alpha+beta=2alpha*beta(according to the question)

we know that,

alpha + beta=-b/a

=-2/k

and,

alpha*beta=c/a

=3k/k

=3

now, according to the question,,

-2/k=2(3)

-2/k=6

-2=6k

k=-2/6

k=-1/3
