Problem:
Multiply and expand $p(x) = -\frac{18 x^2}{\sqrt{\pi }}+\frac{3 x}{\sqrt{\pi }}-\frac{2}{\sqrt{\pi }}$ and $q(x) = \frac{22 x^2}{\sqrt{\pi }}+\frac{2 x}{\sqrt{\pi }}-\frac{7}{\sqrt{\pi }}$
Answer:
$-\frac{396 x^4}{\pi }+\frac{30 x^3}{\pi }+\frac{88 x^2}{\pi }-\frac{25 x}{\pi }+\frac{14}{\pi }$
