In this problem you are asked to convert the general standard form of a quadratic polynomial into the completed square form. Suppose $$f(x)= Ax^2 + Bx + C$$ where $A$, $B$, and $C$ are the coefficients of the quadratic polynomial, and $A\neq 0$. Then $f$ can be written as $$f(x) = a(x-h)^2 + k$$ where
$a=$ ,
$h=$ , and
$k=$ .
Enter your answers as algebraic expressions in $A$, $B$, and $C$. Remember that WeBWorK (and mathematics) is case sensitive so in this case your variables are capital letters, and you must enter them as such.
Hint: Factor out $A$ and complete the square.
