Based on the powers of the variable \(x\) in the polynomial \(5x^2-3x+7\), what is the degree of this expression?
Advertisement
Answer and explanation
Correct answer: 2
The degree of a polynomial is the highest power of its variable. In \(5x^2-3x+7\), the powers of \(x\) are 2, 1, and 0, so the highest is 2. The term \(-3x\) has power 1, but it does not determine the degree. Exam tip: check the greatest exponent.
