Usually when we see 4 different terms we try \" grouping\"
\n" ); document.write( ".
\n" ); document.write( "st +5b -bs -5t,,,rearrange terms
\n" ); document.write( ".
\n" ); document.write( "st - bs +5b-5t
\n" ); document.write( ".
\n" ); document.write( "s(t-b) +5(b-t),,,,change signs 2nd term
\n" ); document.write( ".
\n" ); document.write( "s(t-b) -5(t-b),,,,,,,,,,,,,,now comes hard part,,,,,treat this as s(x) -5(x),,where
\n" ); document.write( ".
\n" ); document.write( " x = (t-b),,,,then x(s-5) is factored form,,,subst back in for x
\n" ); document.write( ".
\n" ); document.write( " ,,,,,,(t-b)(s-5)
\n" ); document.write( ".\r
\n" ); document.write( "\n" ); document.write( "(t-b)(s-5),,,,,answer
\n" ); document.write( ".
