If the equation 3x 2 - kx + 2k = 0 has equal roots, then the value(s) of k is (are) 1. 6 2. 0 only 3. 24 only 4. 0 or 24

Given , 3x 2 - kx + 2k = 0 has equal roots Comparing equation with ax 2 + bx + c = 0 a= 3 , b = -k , c = 2k Since, equation has equal roots ∴ b 2 - 4ac = 0 ∴ Option 4 is the correct option.
