Question

Every quadratic equation $a{x}^2+bx+c=0$ where, a, b, c $\in$ R a$\ne 0$ has.

• A. Exactly one real root
• B. At least one real root
• C. At least two real roots
• D. At most two real roots

Answer 1

The correct option is D At most two real roots

Every quadratic equation $a{x}^2+bx+c=0$ where, a, b, c $ϵ$R a$\ne 0$ can have at most $2$ real roots and can have $0$ real roots when the $2$ roots are complex roots (Imaginary).

Hence, option D is correct.
