High School Algebra I

ALGI.7 Quadratic Equations and Roots

Students use their knowledge of quadratic functions to model and solve problems. Students understand solving quadratics as a process of reasoning and use algebraic properties and rules to form equivalent expressions and equations, which allows them to convert between standard, vertex, and factored form by factoring, completing the equare, and distributing. Students also derive and make use of the quadratic formula.
