How do you multiply these with the foil method? (3t  5v)(4t  4v) Each letter of the word FOIL, tells you what terms to multiply:
First terms (3t)(4t) = 12t2 Outer terms (3t)(4v) = 12tv Inner terms (5v)(4t) = 20tv Last terms (5v)(4v) = 20v2 = 12t2+ 12tv + 20tv + 20v2{used foil method} = 12t2+ 32tv + 20v2{combined like terms}  Algebra House
