Question

Dau COROANA!!!
Descompuneti in factori:
16x^2-25=
81x^2-49y^2=
1,69a^2-1,44b^2=
1-1,96x^2y^2=
x^2-2=
y^2-3=
a^2^b2-7=
2a^2-5=
3x^2-2y^2=
x^2y-121y=
2,25x^2^z^2-y^2z^2=
1,121a^2x-4asupra9b^4x =
4x^2y^2-3y^2=
2ax^2-a=
a^4-b^4=
16x^4-1=
x^4y^4-81=
a^4-4=
(x-1)^4-16=
Aplicati formula diferentelor de patrate si calculati:
(x-2)^2-(x-2)^2=
a^2-(a-3)^2=
4a^2-(2a-1)^2=
(a-b+c)^2-(a+b-c)^2=
