A.CED.A.5: : Rearrange formulas to highlight a quantity of interest, using the same reasoning as in solving equations.

A.REI: : Reasoning with Equations and Inequalities

A.REI.A: : Understand solving equations as a process of reasoning and explain the reasoning.

A.REI.A.1: : Explain each step in solving a simple equation as following from the equality of numbers asserted at the previous step, starting from the assumption that the original equation has a solution. Construct a viable argument to justify or refute a solution method.

A.REI.A.2: : Solve simple rational and radical equations in one variable, and give examples showing how extraneous solutions may arise.

A.REI.B.4: : Solve quadratic equations in one variable.

A.REI.B.4.a: : Use the method of completing the square to transform any quadratic equation in x into an equation of the form (x - p)^2 = q that has the same solutions. Derive the quadratic formula from this form.

A.REI.B.4.b: : Solve quadratic equations by inspection (e.g., for x^2 = 49), taking square roots, completing the square, the quadratic formula, and factoring, as appropriate to the initial form of the equation. Recognize when the quadratic formula gives complex solutions and write them as a ± bi for real numbers a and b.

A.REI.C: : Solve systems of equations.

A.REI.C.5: : Verify that, given a system of two equations in two variables, replacing one equation by the sum of that equation and a multiple of the other produces a system with the same solutions.

A.REI.C.6: : Solve systems of linear equations exactly and approximately (e.g., with graphs), focusing on pairs of linear equations in two variables.

A.REI.C.8: : Represent a system of linear equations as a single matrix equation in a vector variable.

A.REI.C.9: : Find the inverse of a matrix if it exists and use it to solve systems of linear equations (using technology for matrices of dimension 3 × 3 or greater).

A.REI.D: : Represent and solve equations and inequalities graphically.

A.REI.D.10: : Demonstrate understanding that the graph of an equation in two variables is the set of all its solutions plotted in the coordinate plane. Show that any point on the graph of an equation in two variables is a solution to the equation.

A.REI.D.11: : Explain why the x-coordinates of the points where the graphs of the equations y = f(x)and y= g(x) intersect are the solutions of the equation f(x) = g(x); find the solutions approximately.
