# Special Patterns

Multiply the following: Symbolically and by drawing an area model

- \((x-2)(x-2)\)
- \((x+3)^2\)
- \((a+b)^2\)
- \((a-b)^2 \)

What patterns did you observe?

Multiply the following:

- \((x-2)(x^2+2x+4)\)
- \((x+3)(x^2-3x+9)\)
- \((a+b)(a^2-ab+b^2)\)
- \((a-b)(a^2+ab-b^2)\)

What pattern did you observe?

How might this help you with factoring special cases?
