Question

Найдите элемент множества: x2y+x2+180=0

Answer 1

x^2y+x^2+180=0
x^2(y+1)+180=0
X^2y=X^2
$x^{2} y+ x^{2}+180=0 \ x^{2} (y+1)+180=0 \ x neq 0; y= frac{ -x^{2}-180 }{ x^{2} } \ left { {{y=+-6} atop {x=+-6}} right. \ left { {{y=-21} atop {x=+-3}} right. \ left { {{y=-46} atop {x=+-2}} right. \ left { {{y=-181} atop {x=+-1}} right.$
