How many terms are there in (3x^4+2x^2-x+7)?

Answer and explanation

Correct answer: 4

In a polynomial, terms are separated by plus (+) or minus (−) signs. Here the terms are \(3x^4\), \(2x^2\), \(-x\), and \(7\). Therefore, there are 4 terms. The expression \(-x\) counts as one term, so 3 is not correct. Exam tip: Count each complete expression separated by a + or − sign as one term.
