Algebra 2: Reasoning with Equations and Inequalities

A2.AREI.2

Mostly covered
Solve simple rational and radical equations in one variable and understand how extraneous solutions may arise.

A2.AREI.4

Solve mathematical and real-world problems involving quadratic equations in one variable.

A2.AREI.4b

Mostly covered
Solve quadratic equations by inspection, 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. (Note: A2.AREI.4b is not a Graduation Standard.)

A2.AREI.7

Fully covered
Solve a simple system consisting of a linear equation and a quadratic equation in two variables algebraically and graphically. Understand that such systems may have zero, one, two, or infinitely many solutions. (Limit to linear equations and quadratic functions.)

A2.AREI.11

Fully covered
Solve an equation of the form f(x)=g(x) graphically by identifying the x-coordinate(s) of the point(s) of intersection of the graphs of y=f(x) and y=g(x).
