Answer :
To factor out the greatest common factor (GCF) from the polynomial [tex]\(8x^5 - 48x^4 + 16x^3\)[/tex], follow these steps:
1. Identify the GCF of the coefficients:
- The coefficients of the terms are 8, 48, and 16.
- The GCF of these numbers is 8.
2. Identify the smallest power of [tex]\(x\)[/tex] present in each term:
- The terms have powers of [tex]\(x\)[/tex] that are 5, 4, and 3.
- The smallest power of [tex]\(x\)[/tex] is [tex]\(x^3\)[/tex].
3. Combine the GCF of the coefficients and the smallest power of [tex]\(x\)[/tex]:
- The GCF of the entire polynomial is [tex]\(8x^3\)[/tex].
4. Factor out [tex]\(8x^3\)[/tex] from each term:
- For the first term: [tex]\(8x^5\)[/tex], divide by [tex]\(8x^3\)[/tex] to get [tex]\(x^2\)[/tex].
- For the second term: [tex]\(-48x^4\)[/tex], divide by [tex]\(8x^3\)[/tex] to get [tex]\(-6x\)[/tex].
- For the third term: [tex]\(16x^3\)[/tex], divide by [tex]\(8x^3\)[/tex] to get 2.
5. Write the polynomial in factored form:
[tex]\[
8x^5 - 48x^4 + 16x^3 = 8x^3(x^2 - 6x + 2)
\][/tex]
Therefore, the polynomial [tex]\(8x^5 - 48x^4 + 16x^3\)[/tex] factors to [tex]\(8x^3(x^2 - 6x + 2)\)[/tex].
Select choice A:
- [tex]\(8x^5 - 48x^4 + 16x^3 = 8x^3(x^2 - 6x + 2)\)[/tex]
