In the lesson we will solve systems using the substitution method. We will check our work by graphing the equations. Several examples will be completed.

7-5 Factoring – We completed several factoring trinomial problems to understand when to use negative and positive constant values. Then we completed word problems requiring the use of factored quadratics.

Lesson 7-5 Factoring – We learned that when a trinomial is in the form x2 + bx + c, the factors are found by identifying a pair of integer factors of c that have a sum of b and then using the factors to write binomials that have a product equal to the trinomial.

We will solve systems of two equation with two unknowns using a variety of methods. Today we will focus on the substitution method and the row reduction method of a matrix. We will do examples and discuss why we use the methods that we use.
