Answer:
8(k +17)(k -12)
Step-by-step explanation:
A factor of 8 can be removed to give ...
= 8(k^2 +5k -204)
And 204 can be factored as (12)(17), so we can write ...
= 8(k^2 +17k -12k -204) . . . . . split apart the middle term
= 8(k(k +17) -12(k +17)) . . . . . . . factor pairs of terms
= 8(k -12)(k +17)
