1.
(3х+5)(3х-5)-(3х-1)²=9х²-25-9х²+6х-1=6х-26
(2а+1)²-4(а+1)(а-1)=4а²+4а+1-4а²+4=4а+5
3(в-1)²-3в(в-5)=3в²-6в+3-3в²+15в=9в+3=3(3в+1)
(2а-5)(2а+5)-4(а-3)²=4а²-25-4а²+24а-36=24а-61
2.
(х-1)²-(х-3)(х+3)-(х+2)(2х-5)=х²-2х+1-х²+9-2х²+5х-4х+10= -2х²-х+20
при х=136
-2*136²-136+20= - 36876
(2в+1)²-(2в-1)(2в+1)-(2в-3)=4в²+4в+1-4в²+1-2в+3=2в+5
при в= -14
- 2*14+5= - 28+5= - 23
