Find the values of p for which the quadratic equation 4x2 + px + 3 = 0 has equal roots.

Step-by-step explanation:

You need to concern yourself with the +3. That will determine what the equal roots are.

(2x + √3)^2

Now expand this to see what p is. (Kind of a nasty question if you ask me).

4x^2 + 2x*√3 + (√3)^2

4x^2 + 2√3 x + 3

So the answer is p = 2√
