We have the quadratic equation,  3      x    2    −  7  x  −  6  =  0If we used the factorization method,  ⇒  3      x    2    −  9  x  +  2  x  −  6  =  0    ⇒  (  3  x  +  2  )  (  x  −  3  )  =  0    ⇒  3  x  +  2  =  0   or   x  −  3  =  0    ⇒  x  =            −      2        3     or   x  =  3
