7x^4 (Simplify your answer ) Classify the polynomial. The polynomial is a square square square quadratic cubic quartic

To simplify the expression , we can simply write it as since there are no like terms to combine.Now, let's classify the polynomial based on the degree of the highest power of the variable.The degree of a polynomial is determined by the highest power of the variable in the polynomial. In this case, the highest power of the variable is 4.Therefore, the polynomial is a quartic polynomial.So, the classification of the polynomial is:The polynomial is a quartic polynomial.
