The solution to a quadratic equation is x is equals to 3 plus or minus square root of 4 minus 8p all over 4 where p is the element of Q.

Question

Determine the value(s) of p that the roots of the equation are equal and non-real

Answer 1

you need the discriminant to be zero for equal real roots. So,

4-8p = 0

a quadratic with real coefficients cannot have two equal complex roots.
