Question

Determine os numeros reais que Sao solucoes da esquacao x² + 10x = 11x

Answer 1

$x^{2} + 10x = 11x\to \\\\ x^{2} + 10x -11x=0\to \\\\ x^{2} -x=0\\\\ Por\ Evid\^encia:\\\\ x(x-1)=0\\\\\\ x=0\\\\ x-1=0\to x=1\\\\\\\\ S=\{1;0\}$

Answer 2

$x^2+10x-11x=0\\ x^2-x=0\\ x(x-1)=0\\ \boxed{x=0}\\ ou\\ x-1=0\\ \boxed{x=1}$
