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)
