hi,
 factorize the expression first..
            x2 – 14x – 32 = 0
            x^2 - 16x + 2x -32 =0
          x( x - 16 ) +2 ( x -16) = 0
           (x + 2)( x -16) = 0

 did u get it so far ??

yes ok

***[isuru]*** · Answer

so... now we got 
         (x + 2)( x -16) = 0
which means
 either
           (x + 2) = 0 or  ( x -16) = 0
    from that we can say...
            x = -2  or x = 16

I think now u have ur answers lol
