Best ResponseYou've already chosen the best response.1It doesn't make sense to you, right? and "How can I know that way", right? Suggestion: just open parentheses the options (ONE BY ONE), and simplify them to see which one gives you the given expression. That way doesn't ask you the experience or guessing.

Best ResponseYou've already chosen the best response.1I do A for you as example A) \((xy2)^2 +(x+2y)^2\\=(x^2y^24xy+4)+(x^2+4xy+4y^2)\\=x^2+4y^2+x^2y^2+4\) while your give expression is \((x^2+1)(y^2+4)=x^2y^2+4x^2+y^2+4\) They are different, right? hence A is NOT the right answer.
