\n" ); document.write( "\n" ); document.write( "The problem is 2z-1/z+2 > 1
\n" ); document.write( "
\n" ); document.write( "I have tried subtracting the 1 from both sides which make the problem look like this: 2z-1-1/z+2-1 > 0 which will simplify to 2z-2/z+1 > 0 if I'm correct. \r
\n" ); document.write( "\n" ); document.write( "Okay, next I took the factor of the top which I got: 2(z-1) \r
\n" ); document.write( "\n" ); document.write( "so now after I got that I'm not sure if I'm supposed to take 2,-1,and 1 an put them on a number line like it did in the workbook or if I have another step to do. If you can Please help me i would be very happy!

2z-1/z+2 > 1
\n" ); document.write( "(2Z*Z-1)/Z+2>1
\n" ); document.write( "(2Z^2-1)/Z>1-2
\n" ); document.write( "(2Z^2-1)/Z>-1 CROSS MULTIPLY.
\n" ); document.write( "2Z^2-1>-Z
\n" ); document.write( "2Z^2+Z-1>0
\n" ); document.write( "(2Z-1)(Z+1)>0
\n" ); document.write( "2Z-1>0
\n" ); document.write( "2Z>1
\n" ); document.write( "Z>1/2 ANS.
\n" ); document.write( "Z+1>0
\n" ); document.write( "Z>-1 ANS.
