Polynomial Multiplication

Simplifying

2(x-3)

-2(x+2)

-3(2x-3)

(-3x-1) - (4x+2)

(2x²-2x+3) - (3x²+3x-2)

3 + 2x, if x = 4

2x² + 3x - 5, if x = -2

2x - 4 = 8

-x + 4 = 3x -2

2x(x+2)

(x-2)(x-3)

**Factoring**

3x + 3

4x² + 4x +1

Studies show that students who are instructed using the

Concrete-Representational-Abstract approach:

1. develop more precise and more comprehensive mental representations

2. show more motivation and on-task behavior

3. understand mathematical ideas

4. better apply math to life situations
