This question asks for an algebraic expression.

With these types of questions, be sure to use the variables indicated. In your answer, you can also use mathematical expressions for numerical calculations.

Examples:

Type	To get
-3x^2+5	$\displaystyle -{3}{x}^{{2}}+{5}$
(2+x)/(3-x)	$\displaystyle \frac{{{2}+{x}}}{{{3}-{x}}}$
sqrt(x-5)	$\displaystyle \sqrt{{{x}-{5}}}$
3^(x+7)	$\displaystyle {3}^{{{x}+{7}}}$
1/(x(x+1))	$\displaystyle \frac{{1}}{{{x}{\left({x}+{1}\right)}}}$
5/3x+2/3	$\displaystyle \frac{{5}}{{3}}{x}+\frac{{2}}{{3}}$

On the square root, be sure to put parentheses around the input: sqrt(x+3) is OK, but sqrtx+3 or sqrt x+3 is not.

Unless the problem gives specific directions, any algebraically equivalent expression is acceptable. For example, if the answer was $\displaystyle {\left({x}+{2}\right)}{\left({x}+{3}\right)}$, then $\displaystyle {\left({x}+{3}\right)}{\left({x}+{2}\right)}$ and $\displaystyle {\left({3}+{x}\right)}{\left({2}+{x}\right)}$ would also be acceptable.
