[ (m + 1) + 3 (m - 4) ] / [(m - 4) (m + 1)]
( 4m - 11 ) / [ (m - 4) (m + 1 ]

(1) / (m-4) + (3)/(m+1)
= (m+1)+3(m-4) / (m-4)(m+1)
= m+1+3m-12 / (m^2-4m+m-4)
= (4m-11) / (m^2-3m-4)

1 / (m-4) + 3/(m+1) = {1 * (m+1) + 3 * (m-4)} / {(m-4)*(m+1)}
= (m + 1 + 3m - 12) / (m^2 -3m - 4) = (4m - 11) / (m^2 - 3m - 4)

Ok go
...1................3
---------..+...----------
m-4.............m+1
1(m+1) + 3(m-4)
------------------------
.....(m-4)(m+1)
...m+1 + 3m-12
------------------------
.......m²-3m-4
........4m-11
------------------------
.......m²-3m-4
Eye: ....(m-4)(m+1) =--> m²+m -4m-4 =--> m² -3m -4
Bye,bye
