Question

Find the values of k for which the quadratic equation
$9x^{2} - 3kx + k = 0$
has equal roots.

Answer 1

Heya user..!!

Here is ur answer..!!

______________________________________________________________

Answer:

9x²-3kx₊k = 0

By quadratic formula :

a = 9,  b = -3k , c = k

b²-4ac =  ( -3k ) ² - 4 ( 9) (k)

            =  9k²- 36k = 0

           = k²-4k=0

          = k ( k - 4 ) = 0

           = k = 0 or k = 4

Hence :

       ∴       k=4
