1. 8x^6 + 6x^5 + 2x^4
2. 8x^3 - 28x^2 + 4x - 6x^2 + 21x - 3 = 8x^3 - 34x^2 + 25x - 3
3. 2x^4 + 4x^3 + 24x + x^3 + 4x^2 + 24x - 6x^2 - 3x - 18 = 2x^4 + 5x^3 - 2x^2 + 45x - 18
4. 2x^2 + 10x - 4x - 20 = 2x^2 - 14x - 20
5. Distributive: x • x - 3 • x - 2 • x + (-2)(-3) = x^2 - 3x - 2x + 6 = x^2 - 5x + 6
It is hard to explain the "box method" on the computer.

64x^2 + 24x^2 + 8x
