Since the highest power of x is 4, we can expect to have four roots for x.

For the first 2 roots, we have to use the trial-and-error method. Upon finding the 2 roots, we can use the long division or compare coefficient method to further factorise the equation into simpler terms to solve for the roots.

The example I shown is the compare coefficient method. For learning, you can try the long division method :)
