Question

14. If the sum of the zeroes of the quadratic polynomial kx 2 + 2x + 3k is equal to their product, then k is equal to
(a) 1/3
(b) −2/3
(c) −1/3
(d) 2/3​

Answer 1

Answer:

b) -2/3

Step-by-step explanation:

Sum of the zeroes = -b/a

Product of the zeroes = c/a

As sum of the zeroes is equal to the product of the zeroes -

-b/a = c/a

=> -b = c

=> -2 = 3k

=> k = -2/3
