How to Enter Polynomials
Enter coefficients from the highest degree to the lowest, separated by commas. For example:
2, 3, -1represents 2x² + 3x − 11, 0, -4represents x² − 45represents the constant 5
Example: (2x² + 3x − 1) + (x − 2)
= 2x² + 4x − 3
Coefficients: 2, 4, -3
= 2x² + 4x − 3
Coefficients: 2, 4, -3
FAQ
