Introduction

Polynomial factorization is a fundamental concept in algebra that involves breaking down a polynomial into simpler factors. In this article, we will explore the process of factorizing a given polynomial and determine the correct expression that represents the other factor or factors of the polynomial.

Understanding the Problem

The given polynomial is 2x3−3x2−3x+22x^3 - 3x^2 - 3x + 2. We are asked to find the other factor or factors of the polynomial, given that one factor is (x−2)(x-2). To approach this problem, we need to use the concept of polynomial division and factorization.

Polynomial Division

Polynomial division is a process of dividing a polynomial by another polynomial. In this case, we will divide the given polynomial by the factor (x−2)(x-2) to find the other factor or factors.

To perform polynomial division, we can use the following steps:

  1. Divide the leading term of the polynomial (2x32x^3) by the leading term of the divisor (xx) to get the first term of the quotient (2x22x^2).
  2. Multiply the divisor (x−2x-2) by the first term of the quotient (2x22x^2) to get 2x3−4x22x^3 - 4x^2.
  3. Subtract 2x3−4x22x^3 - 4x^2 from the polynomial (2x3−3x2−3x+22x^3 - 3x^2 - 3x + 2) to get x2−3x+2x^2 - 3x + 2.
  4. Repeat the process by dividing the leading term of the new polynomial (x2x^2) by the leading term of the divisor (xx) to get the next term of the quotient (xx).
  5. Multiply the divisor (x−2x-2) by the next term of the quotient (xx) to get x2−2xx^2 - 2x.
  6. Subtract x2−2xx^2 - 2x from the new polynomial (x2−3x+2x^2 - 3x + 2) to get −x+2-x + 2.
  7. Repeat the process by dividing the leading term of the new polynomial (−x-x) by the leading term of the divisor (xx) to get the next term of the quotient (−1-1).
  8. Multiply the divisor (x−2x-2) by the next term of the quotient (−1-1) to get −x+2-x + 2.
  9. Subtract −x+2-x + 2 from the new polynomial (−x+2-x + 2) to get 00.

Finding the Other Factor

After performing polynomial division, we find that the other factor or factors of the polynomial are x2−3x+2x^2 - 3x + 2.

Factoring the Quadratic Expression

The quadratic expression x2−3x+2x^2 - 3x + 2 can be factored using the following steps:

  1. Find two numbers whose product is 22 and whose sum is −3-3. These numbers are −2-2 and −1-1.
  2. Write the quadratic expression as a product of two binomials: (x−2)(x−1)(x-2)(x-1).

Conclusion

In conclusion, the other factor or factors of the polynomial 2x3−3x2−3x+22x^3 - 3x^2 - 3x + 2 are (x−2)(x−1)(x-2)(x-1). This can be verified by multiplying the two factors together to get the original polynomial.

Answer

The correct expression that represents the other factor or factors of the polynomial is:

(x-2)(x-1)

This is option A.

Final Thoughts
