Long division is a method used to divide polynomials by another polynomial of lesser or equal degree. It involves repeated division, multiplication, and subtraction to obtain the quotient and remainder.
congrats on reading the definition of long division. now let's actually learn it.
The divisor must be a polynomial of lesser or equal degree than the dividend.
The result includes both a quotient and a remainder, where the remainder has a lower degree than the divisor.
Align terms with similar degrees for accurate subtraction during each step.
If there is no term for a specific degree in either the dividend or divisor, use zero as its coefficient in alignment.
Long division can verify factorization by checking if the remainder is zero.
