Find the value of k for which the quadratic equation 3x2 + kx + 3 = 0 has real and equal roots

Find the value of k for which the quadratic equation 3x2 + kx + 3 = 0

1.	Find the value of k for which the quadratic equation 3x2 + kx + 3 = 0 has real and equal roots
Answer» For real and equal roots, D = b^2 - 4ac = 0. (for p (x) = ax^2 + bx + c) Therefore, k^2 = 3 * 3 * 4 = 36. k = √36 = 6.//
