giải các phương trình sau:
a)5-(x-6)=4(3-2x) b)\(\dfrac{3x+2}{2}-\dfrac{3x+1}{6}=2x+\dfrac{5}{3}\)
c)\(\dfrac{5x+2}{6}-\dfrac{8x-1}{3}=\dfrac{4x+2}{5}-5\) e)\(x-\dfrac{2x-5}{5}+\dfrac{x+8}{6}=7-\dfrac{x-1}{3}\)
d)x2-5x+6=0 f)(x2-4)-(x-2)(3-2x)=0 g)(2x+5)2=(x+2)2
a: =>5-x+6=12-8x
=>-x+11=12-8x
=>7x=1
hay x=1/7
b: \(\dfrac{3x+2}{2}-\dfrac{3x+1}{6}=2x+\dfrac{5}{3}\)
\(\Leftrightarrow9x+6-3x-1=12x+10\)
=>12x+10=6x+5
=>6x=-5
hay x=-5/6
d: =>(x-2)(x-3)=0
=>x=2 hoặc x=3
