Problem:
Multiply and expand $p(x) = \frac{12 x^2}{\sqrt{\pi }}-\frac{3 x}{\sqrt{\pi }}+\frac{13}{\sqrt{\pi }}$ and $q(x) = \frac{17 x^2}{\sqrt{\pi }}+\frac{8 x}{\sqrt{\pi }}+\frac{18}{\sqrt{\pi }}$
Answer:
$\frac{204 x^4}{\pi }+\frac{45 x^3}{\pi }+\frac{413 x^2}{\pi }+\frac{50 x}{\pi }+\frac{234}{\pi }$
