2/3 x + 1 = 27
subtract 1 from each side
2/3 x = 26
multiply by 3/2
3/2 * 2/3 x = 26 * 3/2
x = 39
notice, there are three terms, therefore is a
trinomial.
the term that has the highest degree, has a degree of 3, therefore the degree of the polynomial as a whole is 3, or a
cubic degree.
so, is a
cubic trinomial.
