Therefore, you need to find the value of
when
in order to solve this exercise.
So, the next step is to substitute
into the function:

And finally, you must evaluate in order to find
.
You get that this is:

The process used is division. If you go to math is fun.com they have a really good step by step example on how to do this. Please give this brainliest answer if I helped.
