What constant term is necessary to complete the perfect square trinomial pictured in the algebra tiles?
gayaneshka [121]
The algebra tiles show two equal factors. They are (x + 4).


Then, the perfect square is the product of the two equal factors, (x + 4) * (x +4).


That is (x + 4)^2.


Then develop that perfect square to find the constant term.


(x + 4)^2 = x^2 + 8x + 16.


That means that the constant term needed to complete the trinomial is 16.
