ax^2+bx+c=0
\n" ); document.write( "one root is 2+√3
\n" ); document.write( "Then... the other root is 2-√3
\n" ); document.write( "x - (2+√3 ))(x - (2-√3)) = 0
\n" ); document.write( "x^2 - (4+1) = 0
\n" ); document.write( "x^2 -4x + 7 = 0
\n" ); document.write( " $\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"$
