x^2+2x=8\r
\n" ); document.write( "\n" ); document.write( "x^2 +2x -8 = 0 \r
\n" ); document.write( "\n" ); document.write( "This can be factorised using middle term factorisation.\r
\n" ); document.write( "\n" ); document.write( "x^2 +4x - 2x -8 = 0\r
\n" ); document.write( "\n" ); document.write( "==> x(x + 4) -2(x + 4) = 0 (taking common factor)\r
\n" ); document.write( "\n" ); document.write( "==> (x-2) (x+4) = 0 \r
\n" ); document.write( "\n" ); document.write( "==> x-2 = 0 \r
\n" ); document.write( "\n" ); document.write( "==> x-2+ 2=0 +2\r
\n" ); document.write( "\n" ); document.write( "==> x= 2\r
\n" ); document.write( "\n" ); document.write( "now consider x +4 = 0 \r
\n" ); document.write( "\n" ); document.write( " ==> x + 4-4 = 0-4\r
\n" ); document.write( "\n" ); document.write( " ==> x = -4\r
\n" ); document.write( "\n" ); document.write( " Hence x = 2 and x = -4 is the solution for the equation.
