Question

the sum of root of quadratic equation is double of their product find k ​

Answer 1

Answer:

K = -1

Step-by-step explanation:

Let's Compare the given eq. by a, b & c

a = 1 , b = 4k , c = k+3

•°• a +b = -b/a = -4k/1 = -4k

•°• ab = c/a = k+3/1 = k+3

•°• a+b = 2ab

-4k = 2(k+3)

-4k = 2k+6

-4k-2k = 6

-6k = 6

k = -6/6

•°• [ k = -1 ]
