The factorised form of k2 - 17 k + 16

= the third one ...

(k-1) (k-16)

because the two numbers in the brackets, - 1 and - 16, must add to give the middle number of the quadratic, - 17, and must multiply to give the integer on the right, 16,

Factor k2 - 17k + 16.(k - 2) (k - 8)(k - 1) (k + 16)(k - 1) (k - 16)

Factor k2 - 17k + 16.

(k - 2) (k - 8)

(k - 1) (k + 16)

(k - 1) (k - 16)
