Lesson Overview



Standards

Subject : Mathematics
Grade : Eight through Twelve
Strand : Algebra II

This discipline complements and expands the mathematical content and concepts of algebra I and geometry. Students who master algebra II will gain experience with algebraic solutions of problems in various content areas, including the solution of systems of quadratic equations, logarithmic and exponential functions, the binomial theorem, and the complex number system.


 
 
STAR California Standards Test Key Standard on the California Standards Test
Substrand:
8.0
Students solve and graph quadratic equations by factoring, completing the square, or using the quadratic formula. Students apply these techniques in solving word problems. They also solve quadratic equations in the complex number system.
