Question

preciso do resultado desta equação
$5x + y = - 3 \\ x \times y = 2$

Answer 1

$\left \{ {{5x+y=-3} \atop {x*y=2}} \right.\\\\y=-3-5x\\\\x(-3-5x)=2\\\\-3x-5x^2=2\\\\-5x^2-3x-2=0\\\\Multiplica~por~-1:\\\\5x^2+3x+2=0\\\\ \Delta=3^2-4(5)(2)\\\\ \Delta=9-20\\\\ \Delta=-11\\\\\\x \notin \mathbb{R}\\\\y \notin \mathbb{R}$
