X^2+4X+1=0 HERE WE NEED TO USE THE QUADREATIC EQUATION
\n" ); document.write( "X=(-B+-SQRT[B^2-4AC])/2A
\n" ); document.write( "X=(-4+-SQRT[4*4-4*1*1])/2*1
\n" ); document.write( "X=(-4+-SQRT[16-4])/2
\n" ); document.write( "X=(-4+-SQRT12)/2
\n" ); document.write( "X=(-4+-3.4641)/2
\n" ); document.write( "X=(-4+3.4641)/2
\n" ); document.write( "X=-.5359/2
\n" ); document.write( "X=-.2679 SOLUTION
