The answer should be x=4/3
That means one whole is cut into 8 parts, and one of those eight parts is considered to be one-eighth of a whole
{think about it like a pizza with 8 slices]
A factor of polynomial P(x) is any polynomial which divides evenly into P(x). For example, x + 2 is a factor of the polynomial x2 – 4. The factorization of a polynomial is its representation as a product its factors. For example, the factorization of x2 – 4 is (x – 2)(x + 2).
