You can put this solution on YOUR website!
x(x-1) = 3x + 2
\n" ); document.write( "=> x^2-x = 3x+2
\n" ); document.write( "=> x^2-x-3x-2 = 0
\n" ); document.write( "=> x^2-4x-2 = 0
\n" ); document.write( "The roots of quadratic equation ax^2+bx+c=0 are
\n" ); document.write( "[-b+sqrt(b^2-4ac)]/2a and [-b-sqrt(b^2-4ac)]/2a;
\n" ); document.write( "Here a=1, b=-4 and c=-2
\n" ); document.write( "The roots of this equation are:
\n" ); document.write( "[4+sqrt(16+8)]/2 and [4-sqrt(16+8)]/2
\n" ); document.write( "=> [4+sqrt(24)]/2 and [4-sqrt(24)]/2
\n" ); document.write( "=> x=2+sqrt(6) and x=2-sqrt(6)
\n" ); document.write( "
\n" ); document.write( "
\n" );
