Hannah factored the expression 24xy + 15y. her work is shown below. 1. gcf (24xy, 15y) = 3y 2. 24xy/3 = 8xy, 15y/3 = 5y 3. 3(24xy + 15y) what are the errors in hannah's work? check all that apply. she divided by 3 instead of the gcf. she found the wrong gcf. she divided wrongly. she didn't complete step 4 and use the distributive property to be sure the expressions are equivalent. she didn't undistribute the gcf from the original expression.
