Simple exercise in collecting terms in different powers of \\(x\\)

Simplify the following expression by combining \"like\" terms.

", "advice": "

The idea is to collect together and combine any terms that are the same kind of term so:

\n

$\\var{b}$ and $\\var{f}$ are ordinary numbers. We can combine them to get $\\var{b+f}$

\n

We can combine $\\var{a}x$ and $\\var{d}x$ to get $\\var{a+d}x$.

\n

There are also $\\var{c}$ times $x^2$. So our answer is:

\n

$\\simplify{{c}x^2+{a+d}x+{b+f}}$
