Which option contains only a linear polynomial?
Answer and explanation
Correct answer: \(3x+10\)
A linear polynomial has the highest power of its variable equal to 1. In \(3x+10\), the highest power of \(x\) is 1, so it is a linear polynomial. \(x^2-2\) is quadratic and \(x^3+1\) is cubic, while \(7\) is a constant polynomial. Exam tip: To identify the degree of a polynomial, look for the greatest exponent of the variable.
