How many terms and what degree does (p(x)=x^4-2x^3+3x^2-4x+5) have?

Answer and explanation

Correct answer: 5 terms, degree 4

The terms of the polynomial are \(x^4\), \(-2x^3\), \(3x^2\), \(-4x\), and \(5\). Hence, it has 5 terms. The degree of a polynomial is the highest exponent of \(x\), which is 4 in \(x^4\). Therefore, the correct answer is 5 terms and degree 4. Do not omit the constant \(5\), as it is also a term. Exam tip: Count terms by separating them at addition and subtraction signs.
