You can put this solution on YOUR website!
x^(2)-4x-7=0
\n" ); document.write( "x=(-b\~(b^(2)-4ac))/(2a)
\n" ); document.write( "x=(-(-4)\~((-4)^(2)-4(1)(-7)))/(2(1))
\n" ); document.write( "x=(4\~((-4)^(2)-4(1)(-7)))/(2(1))
\n" ); document.write( "x=(4\2~(11))/(2(1))
\n" ); document.write( "x=(4\2~(11))/(2)
\n" ); document.write( "x=(4+2~(11))/(2)
\n" ); document.write( "x=2+~(11)
\n" ); document.write( "x=(4-2~(11))/(2)
\n" ); document.write( "x=2-~(11)
\n" ); document.write( "The final answer is the combination of both solutions.
