You can put this solution on YOUR website!
Please post one question is a post.\r

\n" ); document.write( "3x(a-3)-5(3-a) (factorisaton means there should not be + or - between two terms)
\n" ); document.write( "=3x(a-3)-5(-(a-3)) [-(a-3)= 3-a]
\n" ); document.write( "=3x (a-3)+ 5 (a-3) [two - equals +]
\n" ); document.write( "=(a-3)(3x + 5) [taking (a-3) common from both terms]
\n" ); document.write( "(a-3) & (3x+5) are the factors.
