Which option has a linear polynomial as its simplified form?
Answer and explanation
Correct answer: \(x^2+x-x^2+4\)
In option A, \(x^2-x^2=0\), so the expression simplifies to \(x+4\). Its degree is 1, so it is a linear polynomial. Option B has degree 2 and is therefore quadratic, while \(7\) is a constant polynomial. In exams, first combine like terms and then identify the highest power of the variable.
