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