Answer»

Question:-

If the roots of x² +6Kx + K = 0 are equal, the VALUE of K is ___.

ANSWER:-

If roots of a polynomial are equal then

D = 0

{b}^{2} - 4ac \: = 0

here

b = 6k, a = 1 and c = k

So,

→(6k)² - 4.1.k = 0

→36 k² - 4k = 0

→4k ( 9k - 1 ) = 0

So →4k = 0 and →9k - 1 = 0

→k = 0 and→ k = 1/9 ( ans).
