Answer:

Step-by-step explanation:
Given expression:

Let u = (x - y):

To factor a quadratic in the form
find two numbers that multiply to
and sum to
:


Therefore, the numbers are: -6 and -4.
Rewrite
as the sum of these two numbers:

Factor the first two terms and the last two terms separately:

Factor out the common term (u - 2):

Substitute back in u = (x - y):

Simplify:

Answer 27
you have to subtracted 56-29 and you will find your answer
So youve done good so far.
So picking up from : (x^2-x-12)-2(x-4)
-First distribute the (-2) to each factor.
(x^2 - x - 12) -2x + 8
-Then just add variables with the same exponent
x^2 - 3x - 4
Done!
