The fastest way to study is: 1 - try a question 2 - check if its right 3 - if not, figure out what you did wrong 4 - try again Seems so simple but students often miss step 3 and 4!! This factoring calculator for high school students randomly generates practice problems, hides the answer, then shows the step by step solution so you can check your work. Give it a try! https://app.myhomeworkrewards.com/lessons/Gr10/Math/Polynomials/sum_product_factoring.php Happy studying, Gabe
