We have been given,  9      x    2    −  3  x  −  2  =  0  9      x    2    −  6  x  +  3  x  −  2  =  0    3  x  (  3  x  −  2  )  +  1  (  3  x  −  2  )  =  0    (  3  x  +  1  )  (  3  x  −  2  )  =  0Thus,  3  x  +  1  =  0    3  x  =  −  1    x  =            −      1        3  or,  3  x  −  2  =  0    3  x  =  2    x  =      2    3  Thus,   x  =            −      1        3       o  r     x  =      2    3
