- \((x-4)(2x^3-2) = 2x^4-8x^3-2x+8\)
| \(2x^3\) | \(-2\) | |
| \(x\) | \(2x^4\) | \(-2x\) |
| \(-4\) | \(-8x^3\) | \(8\) |
- \((x+2)(2x^3+2x-3) = 2x^4+4x^3+2x^2+x-6\)
| \(2x^3\) | \(2x\) | \(- 3\) | |
| \(x\) | \(2x^4\) | \(2x^2\) | \(-3x\) |
| \(2\) | \(4x^3\) | \(4x\) | \(- 6\) |
- Each term in the first column is multiplied by each term in the first row. After finding the products, like terms are added together.
