Question 117504
Subtract.

1.
5x/x-1  MINUS  5/x-1

2.
2x squared/x-4   MINUS 32/x-4

Because your denominators are the same for both terms in each problem, you will simply be subtracting numerators.

1)
5x-5/x-1

Factor 5 out of the numerator to reduce the answer to lowest terms.
5(x-1)/x-1 = 5

2)
2x^2-32/x-4

Factor 2 out of the numerator to reduce the answer to lowest terms.

2(x^2 - 16)/x-4

Note:  x^2-16 = (x-4)(x+4)

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

=2x+8
