Step-by-step explanation:
We first use the remainder theorem to determine whether
is divisible by
:

the remainder is zero which means
is divisible by
.
Now, we could do polynomial long division to find the quotient, but in this case, it turns out that guessing is easier.

is factored as

which means

which means the quotient is
