Given, .
On taking L.C.M.,
⇒ (x - 2)[6x - 6 - 2x] = x(x - 1)
⇒ (x - 2)(4x - 6) = x(x - 1)
⇒ 4x2 - 6x - 8x + 12 = x2 - x
⇒ 4x2 - x2 - 6x - 8x + x + 12 = 0
⇒ 3x2 - 13x + 12 = 0
⇒ 3x2 - 9x - 4x + 12 = 0
⇒ 3x(x - 3) - 4(x - 3) = 0
⇒ (3x - 4)(x - 3) = 0
⇒ 3x - 4 = 0 or x - 3 = 0
⇒ 3x = 4 or x = 3
⇒ x = or x = 3.
Hence, roots of the given equations are , 3.
