• x = 0 ou x-12=0 --> x=12

  in Qual o resultado da conta x(x-12)= 0? Comment by roberto-frstenau June 2021
• (x+4).(x-1)=5x+20 --> (x+4).(x-1)=5(x+4) --> x-1 = 5 --> x = 6 5y+(y+2)²=3y(y+2) --> 5y = 3y(y+2) -(y+2).(y+2) --> 5y = (3y - (y+2)).(y+2) --> 5y = (2y+2).(y+2)

  in quero saber o calculos do discriminante e o calculos da raiz? Comment by roberto-frstenau May 2021
