You can put this solution on YOUR website!
1. xyz=(-1/a)(4/(1+a)^2)
\n" ); document.write( " V=(-4)/(a(1+a)^2)
\n" ); document.write( "2. -v/4 = 1/(a(1+a)^2) because multiply with negative (-1/4) on both sides.
\n" ); document.write( "3. then, (a(1+a)^2) is (-4/v) it's the reciprocal. \n" ); document.write( "

\n" );
