You can put this solution on YOUR website!
root 3x+4 - root 2x-4=2
\n" ); document.write( "taking squares \r
\n" ); document.write( "\n" ); document.write( "(root 3x+4 - root 2x-4)^2=4
\n" ); document.write( "using(a+b)^2=a^2+2ab+b^2\r
\n" ); document.write( "\n" ); document.write( "3x+4+2root(3x+4)root(2x-4)+2x-4=4
\n" ); document.write( "5x-4=2root(3x+4)root(2x-4)
\n" ); document.write( "(5x-4)^2=4(3x+4)(2x-4)\r
\n" ); document.write( "\n" ); document.write( "25x^2-40x+16=24x^2-16x-64
\n" ); document.write( "x^2-24x+80=0
\n" ); document.write( "so solutions are 4 and 20 (check it at the original equation)
\n" ); document.write( "Answer: solutons are x=4 and x=20 \r
