Integrated Mathematics II: Algebra: Reasoning with Equations and Inequalities (A-REI)

Understand solving equations as a process of reasoning and explain the reasoning

Solve equations and inequalities in one variable

A-REI.4.a

Fully covered
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.4.b

Mostly covered
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.

Solve systems of equations

A-REI.6

Fully covered
Solve systems of linear equations algebraically, exactly, and graphically while focusing on pairs of linear equations in two variables.

A-REI.7

Fully covered
Solve a simple system consisting of a linear equation and a quadratic equation in two variables algebraically and graphically. For example, find the points of intersection between the line y = -3x and the circle x^2 + y^2 = 3.
