Question

How to find value of k when sum of zeroes of cubic polynomial is given

Answer 1

Step-by-step explanation:

ANSWER

In the quadratic polynomial ax2+bx+c

sum of zeroes=−ab

product of zeros=ac

The given quadratic polynomial kx2+5x+3k

According to question,

sum of zeros=product of zeros

⇒−k5=k3k

⇒k=−35
