does anyone know how to foil

(nm+2n) (n-m)


can anyone tell me the answer
 
Is that aluminum foil?
Are we cooking out?
 
Sorry, but if you had been properly taught multiplication you would know:
(a+b)(c+d)=a(c+d)+b(c+d)=ac+ad+bc+db.
If you knew and understood that, couldn’t answer your own question?
LETS DO AWAY WITH “FOIL”!
