3$z^{4}$ - 2$z^{2}$ - 5z; Quartic trinomial
STEP 1: Write out the original expression. 3$z^{4}$ - 5z - 2$z^{2}$ The expression has 3 terms in it, thus classifying itself as a trinomial. STEP 2: Arrange the trinomial into standard form, meaning that the terms are listed from greatest exponent value to the least exponent value. 3$z^{4}$ - 2$z^{2}$ - 5z The degree is the greatest exponent value, and in 3$z^{4}$ - 2$z^{2}$ - 5z, the degree is 4. The name of a trinomial with a degree of 4 is a quartic trinomial.
