Which linear polynomial is in the form (ax)?
Answer and explanation
Correct answer: \(7x\)
A linear polynomial of the form \(ax\) has a non-zero coefficient of \(x\) and no constant term. In \(7x\), \(a=7\) and the constant term is \(0\), so it is of the form \(ax\). Although \(7x+1\) is also linear, it has the constant term \(1\). Exam tip: In \(ax+b\), the polynomial is of the form \(ax\) only when \(b=0\).
