Is the expression %28%282%2F3%29y-1%2F2%29%5E2 ???


%28%282%2F3%29y-1%2F2%29%5E2 Start with the given expression


%28%282%2F3%29y-1%2F2%29%28%282%2F3%29y-1%2F2%29 Expand. Remember, A%5E2=A%2AA


%28%282%2F3%29y%29%28%282%2F3%29y%29%2B%28%282%2F3%29y%29%28-1%2F2%29%2B%28-1%2F2%29%28%282%2F3%29y%29%2B%28-1%2F2%29%28-1%2F2%29 FOIL


%284%2F9%29y%5E2-%281%2F3%29y-%281%2F3%29y%2B1%2F4 Multiply


%284%2F9%29y%5E2-%282%2F3%29y%2B1%2F4 Combine like terms.


So %28%282%2F3%29y-1%2F2%29%5E2 simplifies to %284%2F9%29y%5E2-%282%2F3%29y%2B1%2F4


In other words, %28%282%2F3%29y-1%2F2%29%5E2=%284%2F9%29y%5E2-%282%2F3%29y%2B1%2F4
