roots 2x2+kx+6=0..​

Answer 1

Answer:

I don't know

Step-by-step explanation:

But please follow me

Answer 2

Step-by-step explanation:

for equal roots discriminant is zero

putting formula

D = b^2 - 4ac,

0 = k^2 - ( 4×2×6 ); therefore,

k^2 = 48;. => k = 4√3 or ( -4√3 )

so values are , +4√3 or -4√3
