Chapter 0: Problem 123

Using an example, explain how to factor out the greatest common factor of a polynomial.

Short Answer

Expert verified
Using the polynomial \(12x^3y^2 - 24x^2y^3 + 36x^3y\), we identify the GCF to be \(12x^2y\). Factoring out the GCF from each term in the polynomial gives us \(12x^2y(xy - 2y^2 + 3x)\).

Step by step solution

01

Identify the Polynomial

Let's use the example polynomial \(12x^3y^2 - 24x^2y^3 + 36x^3y\)
02

Identify the GCF

Look at each term in the polynomial and identify the GCF. In this case, the GCF of \(12x^3y^2\), \(-24x^2y^3\), and \(36x^3y\) is \(12x^2y\). This is because each term can be divided evenly by \(12x^2y\).
03

Factor out the GCF

Factor out the GCF from each term in the polynomial. This involves dividing each term in the polynomial by the GCF and writing the results as an expression that is multiplied by the GCF. So, \(12x^3y^2 梅 12x^2y = xy\), \(-24x^2y^3 梅 12x^2y = -2y^2\), and \(36x^3y 梅 12x^2y = 3x\). Our factored polynomial is therefore \(12x^2y(xy - 2y^2 + 3x)\).

Determine whether each statement makes sense or does not make sense, and explain your reasoning. First factoring out the greatest common factor makes it easier for me to determine how to factor the remaining factor, assuming that it is not prime.
