Question

Choose the correct classification of 5x + 3x2 − 7x3 + 2.

a. Third degree polynomial
b. Fourth degree trinomial
c. Sixth degree polynomial
d. First degree binomial

Answer 1

The highest power of x is 3, so this is a third degree multi-term expression, or polynomial. Thus, the answer is A.

Answer 2

Answer: a. Third degree polynomial

Step-to-step explanation:-

• The degree of a polynomial is the highest degree of its individual terms with coefficients not equals to zero.

Given polynomial : $5x+3x^2-7x^3+2$

We can see that the highest degree of x in the given polynomial is 3.

Therefore, the given polynomial $5x+3x^2-7x^3+2$ is classified as a third degree polynomial.
