Capitolo 4, Problema 7
Divide using long division. State the quotient, and the remainder, .
Guida verificata passo dopo passo1
Identify the dividend and divisor: the dividend is \(12x^{2} + x - 4\) and the divisor is \(3x - 2\).
Set up the long division by writing \(12x^{2} + x - 4\) under the division bar and \(3x - 2\) outside.
Divide the leading term of the dividend, \$12x^{2}$, by the leading term of the divisor, \$3x$, to find the first term of the quotient: \(\frac{12x^{2}}{3x} = 4x\).
Multiply the entire divisor \(3x - 2\) by \$4x$ and subtract the result from the dividend to find the new remainder.
Repeat the process: divide the leading term of the new remainder by \$3x$, multiply the divisor by this term, subtract again, and continue until the degree of the remainder is less than the degree of the divisor.

Polynomial Long Division
Polynomial long division is a method used to divide one polynomial by another, similar to numerical long division. It involves dividing the leading term of the dividend by the leading term of the divisor, multiplying the divisor by this result, subtracting, and repeating until the degree of the remainder is less than the divisor.

Introduction to Polynomials
Quotient and Remainder in Polynomial Division
When dividing polynomials, the quotient is the polynomial result of the division, and the remainder is the leftover polynomial with a degree less than the divisor. The division can be expressed as Dividend = Divisor × Quotient + Remainder.

Degree of a Polynomial
The degree of a polynomial is the highest power of the variable in the expression. Understanding degrees is essential in polynomial division because the process continues until the remainder's degree is less than the divisor's degree.
