Answer:
Explanation:
to do this, we first have to look at the same terms expression. So, 14x+14x=28^2 becuase there are two x's. Next we have 15y + 15y which is 30y^2 again with two y's. Now we have -4x+4x which is 0, so that get cancelled. Finally we have 14+14 which is 28. So we have 28x^2+30y^2+24^2+28=284. As you see we can still add same term experssion. The 30y^2+24^2=54^4 beacause there two x's on both expressions. So the answer would be 28^2+54^4+28=284
