    I think you do it like this, you factor both sides as much as you can then you divide.

    oh so you factor before dividing ?

    I guess so. So, factor both sides using synthetic division and then divide.

    this is advanced functions (grade 12) & yes we're solving this algebraically

    i also have a question how can you divide a polynomial of degree 3 by a polynomial of degree 4? like dividing \(\frac{1234}{12345}\)
