A.
6(1 – 3k2) -
B.
6(3k2 – 1) -
C.
6(3k – 1) -
D.
6(1 – 3k)
Correct Answer: Option C
Explanation
(frac{54k^2 – 6}{3k + 1} = frac{6(9k^2 – 1)}{3k + 1})
= (frac{6(3k + 1) – (3k – 1)}{3k + 1})
= 6(3k – 1)
(frac{54k^2 – 6}{3k + 1} = frac{6(9k^2 – 1)}{3k + 1})
= (frac{6(3k + 1) – (3k – 1)}{3k + 1})
= 6(3k – 1)
