na miejsce kropek wstaw znak == lub =\=
(x-2y)(x+2y)...-(2y-x)(2y+x)
(a-b)(a+b)...(b-a)(a+b)
-(4m+a)(1+4m)...(1-4m)(-4m+1)
-(3p-1)(1+3p)...(1-3p)(1+3p)
I weźcie podajcie obliczenia od razu jakie zrobiliście do tego ;)

(x-2y)(x+2y)...-(2y-x)(2y+x)
x^2-4y^2 =\= x^2+4y^2
(a-b)(a+b)...(b-a)(a+b)
a^2-b^2 =\= -a^2+b^2
-(4m+1)(1+4m)...(1-4m)(-4m+1)
-16m^2-8m-1 =\= 1-8m +16m^2
-(3p-1)(1+3p)...(1-3p)(1+3p)
-9p^2+1 =\= 1-9p^2
