Question

for what value of k does the quadratic equation 4x square - 12 x minus 3 equal to zero have no real roots​

Answer 1

Answer:

k = -9

Step-by-step explanation:

4x^2 - 12x - k = 0

For the equation to have no real roots, D = 0

D = b^2 - 4ac = 0

     (-12)^2 - 4(4)(-k) = 0

      144 + 16k = 0

      k = -9
