Don't write the problem in the subject line.

What is the first step to do this??
Doesn't this look silly?

. . $\begin{array}{c} \dfrac{15}{x^4} + \dfrac{2}{x^2} + 2x + 2 \\ \\ \dfrac{15}{x^4} + \dfrac{2}{x^2+2x} + 2 \\ \\ \dfrac{15}{x^4} + \dfrac{2}{x^2+2x+2} \\ \\ \dfrac{15}{x^4 + \dfrac{2}{x^2}} + 2x + 2 \\ \\ \dfrac{15}{x^4 + \dfrac{2}{x^2+2x}} + 2 \\ \\ \dfrac{15}{x^4+\dfrac{2}{x^2+2x+2}} \end{array}$
But I bet it is: . $\frac{15}{x^4} + \frac{2}{x^2+2x+2}$
