Hello from MrBillDoesMath!
Answer: A, C, D
Discussion:
The solution of the quadratic equation ax^2 + bx + c = 0 is
x = ( -b +\- (b^2 - 4ac) ^ (1/2) ) /2a
The expression b^2 - 4ac is called the discriminant, occurs in the numerator of the solution, and also occurs inside a square root (called a radicand).
The question, while intelligible, should be stated more clearly.
Regards, MrB
