(sqrt (x+7)) + (sqrt x) = 3\r
\n" ); document.write( "\n" ); document.write( "Square both sides to get:
\n" ); document.write( "(x+7)+2sqrt(x(x+7))+x = 9
\n" ); document.write( "2sqrt(x^2+7x)=-2(x-1)
\n" ); document.write( "sqrt(x^2+7x)=-(x-1)
\n" ); document.write( "Square both sides to get:
\n" ); document.write( "x^2+7x=x^2-2x+1
\n" ); document.write( "9x=1
\n" ); document.write( "x=1/9
\n" ); document.write( "Checking the answer:
\n" ); document.write( "sqrt((1/9)+(63/9)) + sqrt((1/9))=3
\n" ); document.write( "sqrt(64/9)+sqrt(1/9)=3
\n" ); document.write( "8/3 + 1/3 = 3
\n" ); document.write( "3=3\r
