Final answer:
The polynomial expression 6x⁴ – 3x² + 2 is a quartic polynomial in standard form.
Step-by-step explanation:
The polynomial expression 6x⁴ – 3x² + 2 is a quartic polynomial because it has a degree of 4. It is not a quadratic polynomial because the highest exponent of x is not 2. It is also not a cubic polynomial because the highest exponent of x is not 3. Additionally, it is not a binomial or trinomial because it has more than two or three terms respectively.
The expression is in standard form because the terms are arranged in descending order of the exponents of x.
