Chris was asked to factor out the GCF from the following polynomial. Describe in 1 - 2 sentences the mistake that he made. -4k^7 - 8k^5 + 4k^44k^4 4k^4 4k^4GCF = 4k^4Answer = 4k^4 ( - k^11 - 2k^9 + k^8 )

Answer :

Solution:

Given the polynomial

[tex]-4k^7-8k^5+4k^4[/tex]

To factor out the GCF, we have

[tex]4k^4(-k^3-2k+1)[/tex]

Thus,

[tex]GCF:\text{ 4k}^4[/tex]

Description:

Chris made mistakes in his division.

[tex]\begin{gathered} \frac{-4k^7}{4k^4}=-k^3 \\ \frac{-4k^5}{4k^4}=-2k \\ \frac{4k^4}{4k^4}=1 \end{gathered}[/tex]
