Question

p(x) = kx^2− 3k + x



​

Answer 1

Answer:

given polynomial = kx

2

−2x−3k

if ax

2

+bx+c is a polynomial then its sum of roots is given by

a

−b

and product of roots is given by

a

c

∴ sum of roots of given polynomial =

k

−(−2)

=

k

2

product of roots =

k

−3k

=−3

it is given that sum of roots = product of roots

k

2

=−3

k=

3

−2
