In this lesson, students solve basic quadratic equations using inspection and concrete examples. In the associated Algebra 1 lesson, students solve similar equations with less aid. By providing students with the concrete examples of area of squares and a list of possible solutions, students can begin to see patterns in the solutions so that they may more easily solve basic quadratic equations by inspection later. Students look for and make use of structure (MP7) when they encounter expressions such as and treat it as one quantity.
