Before dividing a polynomial, it is usually important to arrange the divisor in the descending order of powers of the variable(s). To divide a polynomial by a quadratic divisor using the long division algorithm, we divide the polynomial (dividend) with the quadratic term of the divisor to get a term of the quotient. We will then multiply all the terms of the divisor by the term of the quotient and subtract the result from the dividend. The result is divided again by the quadratic term of the divisor to get another term of the quotient. This process is repeated until the quadratic term of the divisor can no longer divide into the dividend. The result after subtracting the product of the last term of the quotient and the divisor is the remainder when the divisor divides the original polynomial. If the remainder is zero, then the divisor is a factor of the original polynomial. Timestamps: 0:00 Intro 0:08 Start of Problem Corrections: 3:34 I made a mistake, it's not -4x but positive 4x.\n
