1. (a2+2)do potegi 2+(2a-3)do potegi 2= a2+ 2a+.....+.....a2-....a+......=.....a2-.....a+.....
2.(3-x)do potegi 2+(x-4)do potegi 2= ....-....x+x2+x2+.....x+....+....x2+....x+....
3.(x+2)do potegi 2- (3x-1)do potegi 2= x2+....x+.....-....x2+.....x-....=....x2+....x+....
(to wsztko x2 a2 jest do potegi)

1) (a²+2)² + (2a-3)² = a⁴ +4a² +4 +4a² -12a +9 = a⁴ +8a² -12a +13
A może miało być:
(a+2)² + (2a-3)² = a²+4a+4 +4a²-12a +9 =5a² -8a +13
2) (3-x)² + (x-4)² = 9-6x+x² +x²-8x+16 = 2x² -14x +25
3) (x+2)² - (3x-1)² = x²+4x+4 -(9x²-6x+1) = x²+4x+4-9x²+6x-1 = -8x² +10x +3
