Answer 1

1)
=3/2(м+3) - (м-2)/(м+3)^2=
3(м+3) -2(м-2)
=----------------------=
2(м+3)^2
3м+9-2м+4
=-----------------=
2(м+3)^2
м+13
=-----------
2(м+3)^2
===============
3)

=1/2(х+1) -(х-1)/3(х^2+2х+1)=
=1/2(х+1) - (х-1)/3(х+1)^2=

3(х+1) - 2(х-1)
=--------------------=
6(х+1)^2
3х+3-2х+2
=---------------=
6(х+1)^2
х+5
=----------
6(х+1)^2
