Answer 1

 

Answer 2

 3            x+3                 2

----   -   ----------   =   - --------

2x          x²+4x              x+4

 

Z: x ≠ 0

    x ≠ -4

D = R \ {-4; 0}

 

 3           x+3               2

----  -   ----------   =   - ------   I*2x(x+4)

2x         x(x+4)           x+4

 

3(x+4) - 2(x+3) = -2*2x

3x+12 - 2x-6 = -4x

x+6+4x = 0 

5x = -6  /:5

x = -6/5

x = -1⅕
