(07.01, 07.02 MC)
An expression is shown below:
4ck2 + 10k- 16ck 40k

Part A: Rewrite the expression by factoring out the greatest common factor. (4 points)

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

Answer 1

a)

The GCF is 2k hence: 2k(2ck + 5k - 8c - 20)

b)

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

After further factorization:

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