Mam rownania i prosze was o pomoc :-)
1)
(√3x-1)(√3+1)-(3x+1)²-(3x+2)²+9x²=
2)
2*(1,5-0,5):2+2,5=
Proszę i dziekuje za pomoc :-)

1)(√3x-1)(√3+1)-(3x+1)²-(3x+2)²+9x²=
3x+√3x-√3-1-(9x²+6x+1)-(9x²+12x+4)+9x²=
3x-1-9x²-6x-1-9x²-12x-4+9x²=
-18x-6-9x²
2)2*(1,5-0,5):2+2,5=
(3-1):2+2,5=
1,5-0,5+2,5=
1+2,5=
3,5
1. (3x²-1)-(9x²+2√3+1)-(9x²+12x+4)+9x²= 3x²-1-9x²-2√3-1-9x²-12x-4+9x²= -3x²-6-2√3
2. 2*(1,5-0,5):2+2,5= 1,5-0,5+2,5=3,5
