If your question is expand (2x+8y)(6n+5m)Then (2x+8y)(6n+5m)=12nx+10mx+48ny+40my

(2x+8y)(6n+5m)
=2x(6n+5m)+8y(6n+5m)
=12xn+10xm+48yn+40ym
=2(6xn+5xm+24yn+20ym)
=2x(6n+5m)+8y(6n+5m)
=12xn+10xm+48yn+40ym
=2(6xn+5xm+24yn+20ym)

(2x+8y)(6n+5m)
=(2x+8y)6n+(2x+8y)5m
=12xn+48yn+10xm+40ym
=10mx+12nx+40my+48ny
=(2x+8y)6n+(2x+8y)5m
=12xn+48yn+10xm+40ym
=10mx+12nx+40my+48ny
