then the value of k is
(a) 3
(6) 4
(c) 6
(d) 12​

Answer 1

Answer:

answer is....

Step-by-step explanation:

b^2 - 4ac = 0 (-12)^2 - 4×3×k =0 144 - 12k = 0 k = 12 hope u understood then mark brainlist

Answer 2

This is the property that if roots are equal then the discriminant is 0. Refer to the image attached .
