Answer 2

HEY MATE!!!!!!

Answer:

Using Shri Dharacharyas formula (quadratic formula)

x = -b±√b²-4ac/2a

Here,

a=2

b=-1

c=0

( here x=k)

Putting values....

k= -(-1)±√(1)²-4×2×0/2×2

=1±√1-0/4

=1±√1/4

=1±1/4

(i)taking + sign

k= 1+1/4 = 2/4 = 1/2

(ii)taking - sign

k= 1-1/4 = 0/4 = 0

Hope it helps.....plzzzzz mark as brainliest....
