Answer:
k = +/-√48
Step-by-step explanation:
4x^2 + kx + 3 = 0
For equal (duplicate) roots the discriminant = 0, so
k^2 - 4*4*3 = 0
k^2 - 48 = 0
k^2 = 48
k = +/-√48
It's 27. When dividing fractions, you multiply the first number by the reciprocal of the second number. The reciprocal of 1/3 is 3/1. 9x3/1=27
