Part B: Factor the entire expression completely. Show the steps of your work (6 points)

PArt A:  2k (2ck + 5k - 8c -20)

Part B: 2k (2c+5) (k-4)

Step-by-step explanation:

Hi, to answer this question we have to analyze the expression given:

4ck2 + 10K2 - 16ck - 40k

Greatest common factor: 2k  

2k (2ck + 5k - 8c -20)

4ck2 + 10K2 - 16ck - 40k

4ck2 - 16ck + 10K2 - 40k

4ck(k -4) + 10k (k-4)

(4ck +10k) (k-4)

2k (2c+5) (k-4)
