You can put this solution on YOUR website!
let require number be x then following the conditions we get an equation
\n" ); document.write( "x+sqrt(x)=6/25 now substitute sqrt(x)=y
\n" ); document.write( " then x =y^2 by squaring both sides
\n" ); document.write( "y^2+y=6/25
\n" ); document.write( "25y^2+25y=6 25 is multiplied on L.H.S
\n" ); document.write( "25y^2+25y-6=0
\n" ); document.write( "25y^2+30y-5y-6=0
\n" ); document.write( "5y(5y+6)-1(5y+6)=0
\n" ); document.write( " (5y+6)(5y-1)=0
\n" ); document.write( "either 5y+6=0 or 5y-1=0
\n" ); document.write( " 5y=-6 5y=1
\n" ); document.write( " y=-6/5 y=1/5
\n" ); document.write( "but from our substitution x=y^2
\n" ); document.write( "either x=(-6/5)^2 or x=(1/5)^2
\n" ); document.write( " x=36/25 or x=1/25 hope this is helpful fo you.
\n" ); document.write( "
\n" );
