1 Answer

5 votes

Answer:

(14x+13)(x-1)

Explanation:

14x²-x-13

14 × 13 = 182

Search for factors of 182 that contain a difference of 1 when subtracted because -x is the same as -1x.

Since 14 × 13 = 182

and

13 - 14 = -1

They are our 2 chosen numbers which will be displayed as :

14x² - 14× + 13x - 13

where -x is replaced by -14x + 13x

Proceed to factorise normally

14x(x-1) + 13(x-1)

Grouping

(14x+13)(x-1)
