What is the expanded form of the algebraic expression 2x(3x^2-4x+1)?

Answer and explanation

Correct answer: 6x^3-8x^2+2x

By the distributive law, multiply 2x by each term inside the bracket: 2x·3x^2=6x^3, 2x·(-4x)=-8x^2, and 2x·1=2x. Therefore, the expanded form is 6x^3-8x^2+2x. Option B does not correctly account for multiplication by 2x, while option D has the wrong sign for the middle term. Exam tip: Multiply the term outside the bracket by every term inside it, including the constant term.
