sqrt(x+5)+sqrt(x-3)=4
\n" ); document.write( "x+5+2sqrt(x+5)sqrt(x-3)+x-3=16 square each side.
\n" ); document.write( "2sqrt(x+5)sqrt(x-3)=14-2x
\n" ); document.write( "sqrt(x+5)sqrt(x-3)=7-x
\n" ); document.write( "(x+5)(x-3)=x^2-14x+49 square each side.
\n" ); document.write( "x^2+2x-15=x^2-14x+49
\n" ); document.write( "16x-64=0
