Question

Choose the correct classification of 2x + 10x2 − x3 by number of terms and by degree.

Third degree trinomial
Fourth degree trinomial
Sixth degree polynomial
First degree binomial

Answer 1

Hello,
answer A
degre=3
nb terms=3

Answer 2

(A)Third degree trinomial

Explanation:

The given expression is:

`2x+10x^2-x^3`

Now, Degree of the expression is defined as the highest power of the variable given in the expression, thus in the given expression that is
`2x+10x^2-x^3` the variable is x and the highest power of x is 3, therefore it is a third degree expression.

Also, Trinomial is an expression which consists of three terms, and also the given expression
`2x+10x^2-x^3` consists of three terms that are
`2x, 10x^2 and -x^3` therefore, the given expression is a third degree trinomial.

Thus, option A is correct.
