Question

Which among the following is the general form of quadratic polynomial ?

• A. $a{x}^3+bx+c$
• B. $a{x}^2+bx+c$, where a,b,c can be any real number
• C. ax²+bx+c where a,b,c are real numbers, and $a\ne 0$
• D. $a{x}^4+bx+c$

Answer 1

The correct option is C ax²+bx+c where a,b,c are real numbers, and $a\ne 0$

$a{x}^2$+$bx$+$c$ is the general form of Quadratic Polynomial , where a , b , c are Real numbers (not imaginary) and the coefficient of $x^2$ should be non zero. If a is zero then the polynomial turns to be linear.
