Answer:
10: Zero-degree monomial.
8x^4: Quartic monomial.
5x² - 7x + 9: Quadratic trinomial.
2x³ + 3: Cubic binomial.
Explanation:
10: This is a constant term, and it can be classified as a zero-degree monomial.
8x^4: This is a monomial with a degree of 4, and it contains one term. It can be classified as a quartic monomial.
5x² - 7x + 9: This is a polynomial with three terms. The highest power of the variable, x, is 2, so it is a quadratic polynomial. Therefore, it can be classified as a quadratic trinomial.
2x³ + 3: This is a polynomial with two terms. The highest power of the variable, x, is 3, so it is a cubic polynomial. Hence, it can be classified as a cubic binomial.
