(4)/(x-3)+(2)/(3-x)

(4)/(x-3) + (2)/(-1)(-3+x)
i factor out a negative 1 from 3-x.

4/(x-3)+ 2/(x-3)

6/x-3

it suppose to be 2/x-3 how i get that?

But when you "factor out" the -1, it has to go somewhere, you can't just drop it , so ...

(4)/(x-3) + (2)/(-1)(-3+x)
= 4/(x-3) - 2/(-3+x)
= 2/(x-3)

remember what I showed you yesterday?
2/-1 = -2/1 = -(2/1)

thanks very much reiny :)

To find the simplified expression, let's go through the steps again:

Original expression: (4)/(x-3) + (2)/(3-x)

Step 1: Factor out a negative 1 from (3-x):
(4)/(x-3) + (2)/(-1)(-3+x)

Step 2: Simplify the expression:
(4)/(x-3) + (2)/(-1)(-3+x)
= (4)/(x-3) + (2)/(x-3)

Step 3: Since the denominators of both fractions are the same (x-3), you can combine the fractions:
= (4 + 2)/(x-3)

Step 4: Add the constants in the numerator:
= 6/(x-3)

So, the simplified expression is 6/(x-3), not 2/(x-3). Double-check your calculations and make sure you didn't make any errors along the way.
