Question

If $a{x}^2+bx+c=0$ is a quadratic equation, then which of the following conditions is always correct?

• A. $a,b,c$ are integers
• B. $a=0$
• C. $a\ne 0$ and $a,b,c$ are real numbers
• D. $b,c\ne 0$

Answer 1

The correct option is C $a\ne 0$ and $a,b,c$ are real numbers

For an equation $a{x}^2+bx+c=0$ to be a quadratic equation, conditions to be satisfied are:
$a\ne 0$ and $a,b,c$ are real numbers
Hence, the correct answer is option (3).
