In my exams, I was asked to calculate value of Quadratic Equation from given value of a, b, c & x.

I'm not good in mathematics. Does that refers to calculating roots of quadratic equation? As far as my knowledge is x is root of Quadratic equation that is already given.

Does value refers to result that we got after solving the equation?

    Without more detail, it's hard to tell. It could just be asking you to evaluate the polynomial $ax^2+bx+c$. Thus, if I said ${a,b,c,x}={1,2,3,4}$ you could compute $1\times 4^2+2\times 4 +3=27$. – lulu Apr 27 '16 at 17:19

    The quadratic function with the parameters $a,b$ and $c$ is $f(x)=ax^2+bx+c$. To calculate the required value you have to input the values of $a,b,c$ and $x$. – callculus42 Apr 27 '16 at 17:20

The general form of a quadratic function is $f(x)=ax^2+bx+c$, where $a,b,c$ are the parameters and $x$ the independent variable.

For given values of $a,b,c$ and $x$ the value of $f(x|a,b,c)$ can be calculated by putting in the corresponding values into the quadratic function.

The general standard form of a quadratic equation is $ax^2+bx+c$.If you have $\{a,b,c,d\}$ know then you might just substitute the required values.
