Which of the following expressions is in expanded form?

Answer and explanation

Correct answer: \(5m-7\)

In \(5m-7\), there is no bracket, power of a binomial, or outside factor left to distribute, so it is already in expanded form. The expressions \(3(x+2)\) and \(x(y+4)\) can be expanded using the distributive property, while \((a+b)^2\) can also be expanded. Exam tip: An expanded expression is usually written as separate terms with no brackets left to multiply out.
