Question

2. Stacey is factoring the expression, 12x^2-4x. After factoring completely, Stacey got 4x(3x-1). How can she check to see if she factored correctly? Explain and show work to support your explanation

Answer 1

She can check that by expanding the factored equation, if she gets the original expression, then the factoring is correct

$4x(3x-1)=12x^2-4x$
