Answer:
x² -2x +4
Step-by-step explanation:
You recognize the dividend as the sum of two cubes. The factorization of that is ...
... a³ + b³ = (a + b)(a² -ab +b²)
In your problem, you have a=x, b =2, so the factorization is ...
... (x³ +8) = (x +2)(x² -2x +4)
When this is divided by (x +2), the result is (x² -2x +4).
You can also use long division or synthetic division to get the same result.
