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
