Question

UpStudy AI · Accepted Answer

Solve the equation $$ z^{2}+18=11z $$.
Solve the quadratic equation by following steps:
- step0: Solve by factoring:
  $$z^{2}+18=11z$$
- step1: Move the expression to the left side:
  $$z^{2}+18-11z=0$$
- step2: Factor the expression:
  $$\left(z-9ight)\left(z-2ight)=0$$
- step3: Separate into possible cases:
  $$\begin{align}&z-9=0\&z-2=0\end{align}$$
- step4: Solve the equation:
  $$\begin{align}&z=9\&z=2\end{align}$$
- step5: Rewrite:
  $$z_{1}=2,z_{2}=9$$
The solutions to the equation $$z^{2}+18=11z$$ are $$z_{1}=2$$ and $$z_{2}=9$$.
The solutions are $$ z=2 $$ and $$ z=9 $$.
