Tell whether the expression 3x^4 -5x +7 is a polynomial. If it is polynomial , find the degrees and determine whether it is a monomial, binomial, or trinomial.

Given:

The polynomial is:

To find:

The degrees and determine whether it is a monomial, binomial, or trinomial.

Solution:

We have,

The highest power of the variable x in the given polynomial is 4. So, the degree of the polynomial is 4.

Monomial: Polynomial with one term.

Binomial: Polynomial with two terms.

Trinomial: Polynomial with three terms.

In the given polynomial, we have three terms . So, the given polynomial is trinomial.

Therefore, the degree of the polynomial is 4 and it is a trinomial.

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.
