- View the expanded form of your polynomial in the results section.
The expanded form of a cubic polynomial is obtained by distributing the terms and combining like terms. The formula for a cubic polynomial in expanded form is:
ax³ + bx² + cx + d = a(x³ + 2x² + x) + b(x² + x) + c(x) + d
| Polynomial | Expanded Form |
|---|---|
| x³ – 2x² + 3x – 4 | x³ – 2x² + 3x – 4 |
| 2x³ – 3x² + 4x – 5 | 2x³ – 3x² + 4x – 5 |
- Always check your answers by plugging them back into the original equation.
- Practice with different coefficients to gain a better understanding of the process.
