What is obtained by simplifying \(x^2+\frac{x}{x}\) for \(x\neq0\)?

Answer and explanation

Correct answer: \(x^2+1\)

Because \(x\neq0\), \(\frac{x}{x}=1\). Therefore, \(x^2+\frac{x}{x}=x^2+1\). Option \(x^2+x\) is incorrect because \(\frac{x}{x}\) equals 1, not \(x\). Exam tip: before cancelling terms in a fraction, ensure that the denominator is non-zero.
