Value of qudaratic equation

Question

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?

Answer 1

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.

Answer 2

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.
