Question

If the sum of the zeros of the quadratic polynomial kx2+2x+3k is equal to the product of its zeros, then k=

(a) 13
(b) 13
(c) 23
(d)23

Open in App
Solution

We know that, in a quadratic polynomial ax2+bx+c

Sum of the zeros =ba

Product of zeros =ca

It is given that, In kx2+2x+3k

Sum of the zeros = Product of zeros

2k=3kk

2k=3

23=k

k=23

Hence, Option c is correct.
