In this lesson, students practice rewriting factored quadratic expressions into standard form with non-zero leading coefficients. Then, students use some information to solve for given information about and . In the associated Algebra 1 lesson, students complete the square for quadratic expressions with a non-zero leading coefficient. Fluency in rewriting quadratic expressions in factored and standard forms supports students in the work of completing the square.

Part of the process for completing the square for quadratics with non-zero leading coefficient involves solving for and using information like that given in the second activity. By isolating that work here, students are supported to carry through the entire process in the associated Algebra 1 lesson.

Looking for and making use of structure (MP7) is essential when expanding a product of binomials into the standard form of a quadratic expression.
