Hi there! It seems you're not multiplying binomials right (you're not using the FOIL method correctly). If you haven't learned about that yet, you can watch a video about it here: https://www.khanacademy.org/math/algebra/introduction-to-polynomial-expressions/multiplying-binomials-2/v/multiplying-binomials
In the picture below, I used the FOIL method with this specific problem.
