a)x² +x =0

x(x+1)=0

* x=0

* x+1=0

      x=0-1

      x=-1

Vậy x=0 hoặc x=-1

2.(x-1) +3(x-2) =x-4

        2x-2+3x-6=x-4

             x+3x-x=-4+2+6

                    3x=4

                     x=\(\frac{4}{3}\)

a, 

x² +x =0

\(\orbr{\begin{cases}x^2=0\\x=0\end{cases}}\)

Vậy x= 0

b,2.(x-1) +3(x-2) =x-4

2x - 2 + 3x - 6 = x - 4 

2x + 3x - x = -4 +6 + 2

4x                = 0

Vậy x = 0
