(+5) – (-3) = 8 or (+5) + ? = 8

Class 1 Review Subtracting Integers:

Problem from Above

Corresponding addition problem

How are they similar?

How are they different?

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)
