We went over examples 1-4 in the textbook on simplifying rational expressions.
Factoring – We practiced factoring a trinomial in the form x2 + bx + c by finding two binomial factors whose product is equal to the trinomial. Then we practiced identifying and using patterns in the signs of the coefficients of the terms of a trinomial expression. Next we practiced factoring out the GCF and then factoring the quadratic equation. Then we eliminated the factors in the numerator and denominator that canceled out to simplify the algebraic expression.
8-1 Key Features of a Quadratic Function – We learned that a quadratic function is a polynomial function in one or more variables in which the highest degree term is of the 2nd degree. The graph is a parabola. The value of the leading coefficient determines both the width of the parabola and the direction the parabola opens (upward or downward).
