What is the degree of the polynomial (9x^2)?
Answer and explanation
Correct answer: 2
In the polynomial \(9x^2\), the exponent of the variable \(x\) is 2. The degree of a polynomial in one variable is the greatest exponent of that variable, so its degree is 2. The number 9 is the coefficient, not the degree. Exam tip: look at the exponent of the variable, not the coefficient.
