Interpret complicated expressions by viewing one or more of their parts as a single entity. For example, interpret P(1+r)^n as the product of P and a factor not depending on P.

Students rewrite quadratic expressions given in standard form, ax2 + bx + c (with a ? 1), as equivalent expressions in completed square form, a(x - h)2 + k. They build quadratic expressions in basic business application contexts and rewrite them in equivalent forms.

Students graph simple quadratic equations of the form y = a(x - h)^2 + k (completed-square or vertex form), recognizing that (h,k) represents the vertex of the graph and use a graph to construct a quadratic equation in vertex form. Students understand the relationship between the leading coefficient of a quadratic function and its concavity and slope and recognize that an infinite number of quadratic functions share the same vertex.
