\n" ); document.write( "\n" ); document.write( "Is the problem sqrt(x+8) = sqrt(5x-4) or (x+8)^2 = (5x-4)^2 ?\r
\n" ); document.write( "\n" ); document.write( "Since you said \"radical\" I'm thinking it's \r
\n" ); document.write( "\n" ); document.write( "1.) sqrt(x+8) = sqrt(5x-4)\r
\n" ); document.write( "\n" ); document.write( "We know if a = b then a^2 = b^2 so we can square both sides of 1.) above:\r
\n" ); document.write( "\n" ); document.write( "2.) [sqrt(x+8)]^2 = [sqrt(5x-4)]^2\r
\n" ); document.write( "\n" ); document.write( "We also know that [sqrt(a)]^2 = a so 2.) becomes:\r
\n" ); document.write( "\n" ); document.write( "x+8 = 5x-4\r
\n" ); document.write( "\n" ); document.write( "Now you can solve the above for x.\r
