ok so use FOIL method

alexandervonhumboldt2 · Answer

(k – 1)(k – 4)=k^2-4k-k+4=simplify

anonymous · Answer

Just use FOIL (First, Outer, Inner, Last):

(k - 2)(k - 1)

First:
k * k = k²

Outer:
k * -1 = -k

Inner:
-2 * k = -2k

Last:
-2 * -1 = 2

Combine the terms:
k² - k - 2k + 2

Answer:
k² - 3k + 2
