4(a)= 3a*3a-2
\n" ); document.write( "4A=9A^2-2
\n" ); document.write( "9A^2-4A-2=0
\n" ); document.write( " $\"A+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"$
\n" ); document.write( "A=(4+-SQRT[-4^2-4*9*-2])/2*9
\n" ); document.write( "A=(4+-SQRT[16+72])/18
\n" ); document.write( "A=(4+-SQRT88)/18
\n" ); document.write( "A=(4+-9.38)/18
\n" ); document.write( "A=13.38/18
\n" ); document.write( "A=.7434 ANS.
\n" ); document.write( "A=(4-9.38)/18
\n" ); document.write( "A=-5.38/18
