What is the degree of (16x^2+5x-3)?
Answer and explanation
Correct answer: 2
The degree of a polynomial is the highest exponent of its variable. In the terms 16x^2, 5x, and -3, the powers of x are 2, 1, and 0 respectively. Hence, the highest power is 2, so the degree of the polynomial is 2. The number 16 is a coefficient, not the degree. Exam tip: For degree, look at the greatest power of the variable, not its coefficient.
