Answer 1

(x-2)(x-2)=x la2-4x+4
(x+2)(x+2)= x la 2 +4x+4
(x+4)(x+4)=x la2+8x+16
x la 2 -4x+4+3xla2+12x+12 mai mare si =x la2 +8x+16
4x la2+8x+16 m m =x la 2+8x+16
4x la2-x la2+8x-8x=16-16
3x la 2=0
2).9-6x+x la 2   -  8x la2-8x-2 mai mic si =  54x la 2+36x+6
-7 x la2-14x+7 m m =54 x la2+36x+6
-7x la2-54 x la2-14x-36x m m =6-7
-61 x la 2-50x m m =-1

3).4x la2+12x+9+18 x la2+24x+8 mai mare =4x la2+16x+16
 
22x la2+36x+17 m m= 4x la2+16x+16
22xla2-4x la2+36x-16x m m =16-17
18 x la2+20x m m = -1
