4: x^2-3x+xy-3y=0
=>x(x-3)+y(x-3)=0
=>(x-3)(x+y)=0
=>x=3 và x+y=0
=>x=3 và y=-3
6: (x-2)^2-5(2-x)=0
=>(x-2)^2+5(x-2)=0
=>(x-2)(x-2+5)=0
=>(x-2)(x+3)=0
=>x=-3 hoặc x=2
8: x^2(x-3)+18-6x=0
=>x^2(x-3)-6(x-3)=0
=>(x-3)(x^2-6)=0
=>x=3 hoặc \(x=\pm\sqrt{6}\)
10: (x-5)^2-(x-2)^2=0
=>(x-5-x+2)(x-5+x-2)=0
=>-3(2x-7)=0
=>2x-7=0
=>x=7/2
12: x^2(x-3)-4x+12=0
=>x^2(x-3)-4(x-3)=0
=>(x-3)(x^2-4)=0
=>(x-3)(x-2)(x+2)=0
=>\(x\in\left\{3;2;-2\right\}\)
14: 3x^2-7x-10=0
=>3x^2-10x+3x-10=0
=>(3x-10)(x+1)=0
=>x=10/3 hoặc x=-1
