Brainlies ! an expression is shown below: 4ck^2 + 10k^2 − 16ck − 40k part a: rewrite the expression so the gcf is factored completely. (4 points) part b: rewrite the expression completely factored. show the steps of your work. (6 points)

Part athe gcf is 2k. rewrite each term so that 2k is factor, and then use the distributive property to pull out the 2k terms4ck^2 + 10k^2 - 16ck - 40k2k*2ck + 2k*5k - 2k*8c - 2k*202k(2ck + 5k - 8c - 20)after pulling out the gcf 2k, we are left with 2k(2ck + 5k - 8c - 20)part bstart with the result from part a. continue factoring using the factor by grouping method.2k*(2ck + 5k - 8c - 20)2k*((2ck + 5k) + (-8c - 20))2k*(k(2c + 5) + (-8c - 20))2k*(k(2c + 5) - 4(2c + 5))2k(k - 4)(2c + 5)so the original expression completely factors to 2k(k - 4)(2c + 5)
