I can subtract polynomials by combining like terms.
- 1
When subtracting polynomials, the key principle is to add the opposite of the polynomial being subtracted.
- 2
To subtract polynomials, you must first distribute the negative sign to every term in the second polynomial, which inverts each term's sign.
- 3
After distributing the negative sign, the next step is to combine like terms, which are terms that have the same variable raised to the same exponent.
