Which description is correct for the polynomial 3x3+4x2−7?

quadratic trinomial

cubic binomial

quartic trinomial

cubic trinomial

This would be a Cubic Trinomial; The number of terms are 3 and the degree is 3.

Cubic trinomial

Step-by-step explanation:

The first word expresses the maximum exponent of our polynomial . In this case,  cubic means that our variable (x) has, as higher degree, 3. If the highest degree would have been 2, we say we have a quadratic polynomial. Quartic doesnt exist.

The second term refers to the number of independent expressions that constitute our function. In the example, we have 3 expressions 3x^3 , 4x^2 and -7. As there are three expressions, we say that the polynomial is a trinomial. If the expression had only two terms it would be a binomial.

0/5 is 0, 2/0 is undefined, and 0/0 is indeterminate.
