1+sqrt(x+5)=sqrt(x+12) square botgh sides.
\n" ); document.write( "1+2sqrt(x+5)+x+5=x+12
\n" ); document.write( "x-x+2sqrt(x+5)=12-5-1
\n" ); document.write( "2sqrt(x+5)=6 square both sides.
\n" ); document.write( "4(x+5)=36
\n" ); document.write( "4x+20=36
\n" ); document.write( "4x=36-20
\n" ); document.write( "4x=16
\n" ); document.write( "x=16/4
\n" ); document.write( "x=4 ans.
\n" ); document.write( "Proof:
\n" ); document.write( "1+sqrt(4+5)=sqrt(4+12)
\n" ); document.write( "1+sqrt9=sqrt16
\n" ); document.write( "1+3=4
\n" ); document.write( "4=4\r
