12.1 Simplifying Rational Expressions Rational Expression: - A rational expression is an algebraic FRACTION whose numerator and denominator are polynomials. - To simplify a rational expression (a fraction), you factor the numerator and denominator and eliminate any common factors. Numerator and Denominator are Polynomials... ... and how do we factor polynomials? - Binomials - 1) GCF, 2) Difference of squares - Trinomials - 1) GCF, 2) Product-Sum (Box method) - 4 + terms - 1) GCF, 2) Factor by Grouping Assignment: P. 664 (#14-28) skip any two

11.2 Roots

Roots - the solutions of quadratic equations.
***Found by locating the x-intercepts.

Homework: Keep graph sheet; Look at example #2 and circle
the steps you think we don't need to do.

11.1 (cont'd)

Vertex - middle/on A.O.S./highest or lowest part
Axis of Symmetry (A.O.S.) - identical on both sides; vertex
is on it

Quadratic - Variable is squared; y = ax^2 +bx + c

Assignment: p. 615 (#19-24) and #(30-32)

11.1 Graphing Quadratic Functions

I can...
**find the equation of the axis of symmetry and the
coordinates of the vertex
**graph a quadratic function

QUADRATIC FUNCTION - A quadratic function is an equation in
the form of:

y + ax^w + bx + c; where a does not equal 0

To find the axis of symmetry:
~vertex is ALWAYS on it
~parabola is identical on both sides, like a mirror

X = -B/2a

Positive parabola - opens up (like a smiley face)
Negative parabola - opens down (like a frown face)
