This self-checking worksheet takes the student through absolute value quadratic functions involving factoring ... twice!! What is not to love about these problems??!!?? All problems work out so both sets of quadratic equations factor neatly. The leading coefficient is always one. The very last problem is a linear, not a quadratic. I added this problem to see if my students were on their toes. Some problems have extraneous solutions, so the student must check each solution. When finished, the students will find a bit of advice.
