Ex 5 punctul a va rog !!!!

Answer 1

Răspuns

(x+1)/(x+3) - (x-5)/2(x-3) -4x/2(x²-9) - (x-2)/2(x+3)= -1/2(x+3)

Explicație pas cu pas:

[2(x+1).(x-3) - (x-5).(x+3) - 4x - (x-2).(x-3)]/2(x²-9)=

(2x²-6x+2x-6 - x²-3x + 5x +15 -4x -x² +3x +2x-6)/2(x²-9) =

( -x +3 )/2(x²-9)=-(x-3)/2(x²-9) = -1/2(x+3)
