A, 2x(x-1)=3x-3 B.x2-6x=0 C.x(x-3)-x2+5=0 D. 3x+2(5-x)=0 E. (X+2)2=(x-2)(x+2) Giúp e vs mai em thi r

a, 2x(x-1)=3x-3

⇒2x(x-1)-3x+3=0

⇒2x(x-1)-3(x-1)=0

⇒(x-1)(2x-3)=0

⇒\(\left[ \begin{array}{l}x-1=0\\2x-3=0\end{array} \right.\) =>\(\left[ \begin{array}{l}x=1\\2x=3\end{array} \right.\) =>\(\left[ \begin{array}{l}x=1\\x=3/2\end{array} \right.\) 

Vậy x=1, x=3/2

b, x²-6x=0

⇒x(x-6)=0

⇒\(\left[ \begin{array}{l}x=0\\x-6=0\end{array} \right.\) =>\(\left[ \begin{array}{l}x=0\\x=6\end{array} \right.\) 

Vậy x=0, x=6

c, x(x-3)-x²+3=0

⇒x(x-3)-x(x-3)=0

⇒(x-3)(x-x)=0

⇒(x-3).0=0

⇒x-3=0

⇒x=3
