Consider the following polynomial: – 9 + x4 – 5x + 2x3 + 5xThis polynomial can be classified as
Answer
A
fifth degree.
B
fourth degree.
C
monomial.
D
binomial.
E
trinomial.
Explanation
Combine like terms: −5x and +5x cancel, leaving x⁴ + 2x³ − 9. The highest exponent is 4, so it is fourth degree, and the three nonzero terms make it a trinomial.
