I'm have problems solving this equations can someone me

Well, like many problems, I think it would be best to start with writing the information we already know. First, of all we know

Using this information, we can create the following equations:

Simplifying, we get the following:

Now, let's solve one of the equations for :

Now, we can substitute in 55 for to get the following:

Now we need to solve . We already know that is a zero of the equation, so let's divide our entire equation by using synthetic division. This is a little hard to show here, but our result is:

Now, we can solve by factoring:

Our final zeros are
