Question

Which of the following conditions is incorrect for the standard form of a Quadratic Equation, $a{x}^2+bx+c=0$?

• A. $a,b,c$ Real Numbers
• B. $a$ is NOT EQUAL to $0$
• C. $b$ is NOT EQUAL to $0$
• D. None of these

Answer 1

Answer: (C)

$b$ is NOT EQUAL to $0$

We know that the standard form of a Quadratic Equation is $a{x}^2+bx+c=0$, where $a,b,c\in$ Real Numbers and $a\ne 0$. Both options a and b are necessary conditions for any standard form of a quadratic equation. But option c states that b is NOT EQUAL to $0$, which is not any of the necessary conditions for the standard form of any quadratic equation, Hence option c is the incorrect option amongst the given options.
