$\"%283%5E%282x%29%29+%2B+%283%5E%28x%2B1%29%29+-+4+=+0\"$
\n" ); document.write( " $\"3%5E%282x%29+%2B+3%5Ex%2A3%5E1+-+4+=+0\"$
\n" ); document.write( " $\"3%5E%282x%29+%2B+3%5Ex%2A3+-+4+=+0\"$
\n" ); document.write( "Suppose: $\"p=3%5Ex\"$ , so that:
\n" ); document.write( " $\"p%5E2%2Bp%2A3-4=0\"$
\n" ); document.write( " $\"p%5E2%2B3p-4=0\"$
\n" ); document.write( "(p+4)(p-1)=0
\n" ); document.write( "p+4=0 or p-1=0
\n" ); document.write( "p=-4 or p=1
\n" ); document.write( "--------------------
\n" ); document.write( "substitute p=-4 to $\"p=3%5Ex\"$ :
\n" ); document.write( " $\"p=3%5Ex\"$
\n" ); document.write( " $\"-4=3%5Ex\"$ ------>There is no solution for x
\n" ); document.write( "-----------------------------------------------
\n" ); document.write( "Substitute p=1 to $\"p=3%5Ex\"$ :
\n" ); document.write( " $\"p=3%5Ex\"$
\n" ); document.write( " $\"1=3%5Ex\"$
\n" ); document.write( " $\"3%5E0=3%5Ex\"$
\n" ); document.write( "x=0
\n" ); document.write( "_________________________________________________
\n" ); document.write( "Thus, solution for this problem is x = 0 \n" ); document.write( "
