A. 1 real root, 1 imaginary root
B. 2 real roots, 2 imaginary roots
C. 2 real roots
D. 4 real roots.
I have x^2 = 625
x = 25
answer: 2 real roots (25 or 25) Is this correct?
Thanks

Yes. A quadratic has two roots. In this case both are real. If one were complex, the other would be too. (The complex conjugate)
