Mn giúp mik lm câu 32-> 35 đc khum ak Mik camon😢

Answer 1

32: \(\dfrac{x}{a-2}+\dfrac{5a-4}{3a^2-6a}-\dfrac{2}{3a}\)

\(=\dfrac{3ax+5a-4-2a+4}{3a\left(a-2\right)}=\dfrac{3ax-3a}{3a\left(a-2\right)}=\dfrac{x-1}{a-2}\)

33: \(=\dfrac{3a+3a+ax-x-ax+x}{3a\left(a-1\right)}\)

\(=\dfrac{6a}{3a\left(a-1\right)}=\dfrac{2}{a-1}\)

35: x/a-2+(2x-ax-a)/(2a-a^2)-x/a

\(=\dfrac{xa-2x+ax+a-ax+2x}{a\left(a-2\right)}\)

\(=\dfrac{xa+a}{a\left(a-2\right)}=\dfrac{x+1}{a-2}\)
