Question

which constant should be added and subtracted to solve the quadratic equation 4xsquare - root 3x-5=0 by the method of completing the square​

Answer 1

Answer:

If you have a x² + b x + c = 0 and you're completing the square, you'll want to add/subtract b²/4a. Here, we have a = 4 and b = -√3, so we need to add/subtract 3 / 16.

Answer 2

Answer:

nothing should be added as we can do it by complex numbers directly
