Solving Systems with Matrices and Factoring Expressions

Precalculus will begin applying matrices to the solution of systems of equations.  It is an exciting week!  Please find the slides for the upcoming week below (starting with ppt5), a keystroke guide for matrices, as well as the homework.  We will have another investigation from the College Board's Springboard materials.  We completed "Gems in the Matrix" and "How Much Wood Do You Need," and will end with an investigation of mixtures.  Continue to focus on argument and explaining how matrices can help us manage and manipulate large sets of information.

Algebra II will hone their factoring skills and will be introduced to the basics of rational expressions.  After next week algebraic basics is over and we will be moving onto linear functions and piecewise functions.  Please find the notes from the week below (factoring is ppt2), factoring reference sheets, and the homework.
