Question

Subtract the rational expressions.

x2/x-1.
6x-7/ x-7

Answer 1

`((x -7)(x-1))/(y)`

Explanation:

`x^(2)` / x - 1 - 6x - 7/ x - 1

(it's the equation shown in the picture, you might have typed it wrong on your question)

The equation has the same denominator so, it will become:

`(x^(2) - 6x - 7)/(y)`

Which factors into:

`((x -7)(x-1))/(y)`
