MizoriesKun √b +√a √b-√a b+a (√b +√a )(√b +√a ) -(√b -√a )(√b -√a )
(--------- - ------------ ) * -------- = (-------------------------------------------------------------- ) *
√b-√a √b+√a   √ab (√b +√a )(√b -√a )

1) (2х+1)(2-х) -2(2х+1) (2х+1)(2-х-2)
   ----------------------------- = ---------------------
(2-х)(2+х) (2-х)(2+х)

2) (2х+1)(-х) 2х+1 (2х+1)(-х) -(2-х) х
