Answer:
<em>B, C, E</em>
Step-by-step explanation:
If we were to consider expanding the expression ( x + y )^2, take a look at the procedure below;
Thus, the <em>first option is incorrect</em>
x^2 + 2xy + y^2 is similar to the result of the expansion of ( x + y )^2, so the <em>second option is correct</em>
Grouping like terms, x( x + y ) + y( x + y ) = ( x + y )^2, and thus the <em>third option is correct</em>
As noted before, x^2 - 2xy + y^2 is not x^2 + 2xy + y^2, so the<em> </em><em>fourth option is incorrect</em>
And thus, <em>Option E is correct</em>!
