%2811x%2B3y%29%28x%2B4y%29 Start with the given expression

Remember, when you FOIL an expression, you follow this procedure:


Multiply the First terms:%2811x%29%2A%28x%29=11x%5E2


Multiply the Outer terms:%2811x%29%2A%284y%29=44xy


Multiply the Inner terms:%283y%29%2A%28x%29=3yx


Multiply the Last terms:%283y%29%2A%284y%29=12y%5E2


11x%5E2%2B44xy%2B3yx%2B12y%5E2 Now collect every term to make a single expression



11x%5E2%2B47xy%2B12y%5E2 Now combine like terms




---------------------
Answer:
So %2811x%2B3y%29%28x%2B4y%29 foils and simplifies to 11x%5E2%2B47xy%2B12y%5E2

In other words, %2811x%2B3y%29%28x%2B4y%29=11x%5E2%2B47xy%2B12y%5E2
