Class 1: Review Show =1 =1/2 =1/4 =1/3 =1/6 =1/12 =1/24
Class 1: Review Show =1 =1/2 =1/4 =1/3 =1/6 =1/12 =1/24 =1/8
Class 1 Review Subtracting Integers: show (+5) – (-3) (+5) – (-3) = 8 or (+5) + ? = 8
Class 1 Review Subtracting Integers: Corresponding addition problem How are they similar? How are they different? Problem from Above
Multiplying Polynomials (x – 1)(x +4) (x – 1)(x +4)=x2+3x-4
Dividing Polynomials x2 + 5x +6 x + 2
Dividing Polynomials x2 + 5x +6 x + 2
Dividing Polynomials x2 + 5x +6 x + 2 = x+3
Factoring Polynomials x2 – 5x + 6
Factoring Polynomials x2 – 5x + 6--- make a rectangle with the squares
Factoring Polynomials x2 – 5x + 6 = (x-2)(x-3)
