Solve the equation $$ x^{2}-9x-22=0 $$.
Solve the quadratic equation by following steps:
- step0: Solve by factoring:
  $$x^{2}-9x-22=0$$
- step1: Factor the expression:
  $$\left(x-11ight)\left(x+2ight)=0$$
- step2: Separate into possible cases:
  $$\begin{align}&x-11=0\&x+2=0\end{align}$$
- step3: Solve the equation:
  $$\begin{align}&x=11\&x=-2\end{align}$$
- step4: Rewrite:
  $$x_{1}=-2,x_{2}=11$$
The zeros of the quadratic function $$y=x^{2}-9x-22$$ are $$x=-2$$ and $$x=11$$.
The zeros are $$x=-2$$ and $$x=11$$.
