When a quadratic equations have equal roots then it's discriminant will be equal to Zero.
D = 0
and
D = b² - 4ac
0 = ( - k√3 )² - 4 × 3 × 4
0 = 3k² - 48
48 = 3k²
16 = k²
√16 = k
± 4 = k
So, Value of k will be 4 Or - 4
D = 0
and
D = b² - 4ac
0 = ( - k√3 )² - 4 × 3 × 4
0 = 3k² - 48
48 = 3k²
16 = k²
√16 = k
± 4 = k
So, Value of k will be 4 Or - 4
