What is the degree of (6x^2+5x^7-3x^4)?
Answer and explanation
Correct answer: 7
The degree of a polynomial is the greatest exponent of the variable among its terms. In the given polynomial, the exponents of x are 2, 7, and 4; the greatest is 7. Therefore, the degree is 7. Note that 5 is the coefficient of x^7, not the degree. Exam tip: compare the exponents of the variable, not the coefficients.
