Classify each polynomial by degree and number of terms (lesson 17.1) z^2-12

zalisa [80]

Answer:

The degree is "2" and the number of term is "2(binomial)"

Step-by-step explanation:

Considering the expression $z^2-12$

Largest sum of any term is known as the degree.

Now simplify as follows,

$z^2-12$

So, the degree is 2 because the largest sum of power is known as degree

And the number of terms is two (2) it means it is binomial.

∵ The degree is "2" and the number of term is "2(binomial)"
