Which linear polynomial is obtained by simplifying (2(3x-1))?

Advertisement

Answer and explanation

Correct answer: \(6x-2\)

Using the distributive property, \(2(3x-1)=2\times 3x-2\times 1=6x-2\). Therefore, \(6x-2\) is correct. In \(6x+2\), the negative sign of the constant term has been changed incorrectly. Exam tip: multiply the number outside the bracket by every term inside it.
