Question

Which of the following is a product of the rational expression x/x-5•2x/x+4

Answer 1

-5

Explanation:

First you need to divide and reduce

any expression divided by itself equals 1 (so x/x = 1)

1 - 5 × 2x/x + 4

Reduce the fracton with x

1 - 5 × 2 + 4

Then multiply the numbers

1 - 10 + 4

-5
