What is the expanded form of the expression \(5(x-1)\)?

Answer and explanation

Correct answer: \(5x-5\)

Using the distributive law, multiply \(5\) by each term inside the bracket: \(5(x-1)=5\times x-5 imes1=5x-5\). Therefore, option B is correct. In option A, \(-1\) has not been multiplied by \(5\). Exam tip: When removing brackets, multiply the outside factor by every term inside.
