Question

Please answer the question in the picture

Answer 1

Option C

step explanation:

`(x-7)/(x^(2)+8)-(x^(2)-x +6 )/(x^(2)+8) = (x-7 - [x^(2)-x+6])/(x^(2)+8)`

`= (x - 7 - x^(2)+x - 6)/(x^(2)+8)\\\\\\=(x +x -7-6 -x^(2))/(x^(2)+8)\\\\\\=(2x - 13 - x^(2))/(x^(2)+8)\\\\\\=(-x^(2)+2x - 13)/(x^(2)+8)`
