What is the simplified form of (2x -25)/(2x -3x -10)?

I suspect a typo and you meant:

(x^2 - 25)/(x^2 - 3x - 10) , since that factors nicely into
(x+5)(x-5)/( (x-5)(x+2)
= (x+5)/(x-2) , x ≠ 5

Yes a typo - thanks

To find the simplified form of the expression (2x - 25) / (2x - 3x - 10), we can start by combining the like terms in the denominator.

The expression can be rewritten as (2x - 25) / (-x - 10).

Next, we can factor out a -1 from the denominator:

(2x - 25) / [(-1)(x + 10)].

Now, we can cancel out the common factor of -1:

(2x - 25) / (x + 10).

Therefore, the simplified form of the expression (2x - 25) / (2x - 3x - 10) is (2x - 25) / (x + 10).
