Question

please help i need to factor this polynomial 4k(3k-2)-(3k-2)

Answer 1

well expand and simplify 12k^2 - 8k - 3k + 2

12k^2 -11k + 2

to factorise... multiply the coeffiecient of k^2 by the constant

12 x 2 = 24... find the factors of 24 that add to - 11 -8, -3

then

\[((12k - 8)(12k - 3))/12 \]

simplify

\[(4(3k - 2)3(4k - 1))/12\]

(3k -2)(4k -1)
