Question 22
If $a_2\ne0$ and $r,$ $s$ are the roots of $a_0+a_1x+a_2x^2=0,$ then the equality
$$
\begin{aligned} a_0+a_1x+a_2x^2 &=a_0\left(1-\frac xr\right)\\ &\quad\cdot\left(1-\frac xs\right) \end{aligned}
$$
holds:
$$
\begin{aligned} a_0+a_1x+a_2x^2 &=a_0\left(1-\frac xr\right)\\ &\quad\cdot\left(1-\frac xs\right) \end{aligned}
$$
holds:
