Question

2x²-x+2=2 in R ecuatia

Answer 1

$2x^2-x+2=2=\ \textgreater \ 2x^2-x+2-2=0=\ \textgreater \ 2x^2-x=0=\ \textgreater$$=\ \textgreater \ x(2x-1)=0=\ \textgreater \ \left \{ {{x=0} \atop {2x-1=0}} \right. =\ \textgreater \ \left \{ {{x_1=0} \atop {x_2=1/2}} \right.$

Answer 2

2x²-x+2=2
2x²-x=0
x*(2x-1)=0

x=0
2x=1-0

x=0
x=1/2


x₁=0
x₂=1/2
