%2811x+%2B+3y%29+%28x+%2B+4y%29

Step 1. Multiply using the FOIL (multiply First, Outer, Inner, Last terms) method.

%2811x+%2B+3y%29+%28x+%2B+4y%29=11x%2Ax%2B11x%2A4y%2B3y%2Ax%2B3y%2A4y

%2811x+%2B+3y%29+%28x+%2B+4y%29=11x%5E2%2B44xy%2B3yx%2B12y%5E2

Step 2. Combine like terms and in this example they are 44xy%2B3xy=47xy

%2811x+%2B+3y%29+%28x+%2B+4y%29=11x%5E2%2B47xy%2B12y%5E2

Step 3. ANSWER: %2811x+%2B+3y%29+%28x+%2B+4y%29=11x%5E2%2B47xy%2B12y%5E2

I hope the above steps and explanation were helpful.
