Step-by-step explanation:
x/(x−4)(x−5)+1/(x−5)
Express
x−4
x
(x−5) as a single fraction.
x−4
x(x−5)
+
x−5
1
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of x−4 and x−5 is (x−5)(x−4). Multiply
x−4
x(x−5)
times
x−5
x−5
. Multiply

times
x−4
x−4
.
(x−5)(x−4)
x(x−5)(x−5)
+
(x−5)(x−4)
x−4
Since
(x−5)(x−4)
x(x−5)(x−5)
and
(x−5)(x−4)
x−4
have the same denominator, add them by adding their numerators.
(x−5)(x−4)
x(x−5)(x−5)+x−4
Do the multiplications in x(x−5)(x−5)+x−4.
