How many unit tiles need to be added to the expression x2 + 4x + 3 in order to form a perfect square trinomial?

The number to be added in an expression x2 + 4x + 3 in order to make it as a perfect trinomial is 1, we need to add 1 to 3 to make it 4 since 4 is a perfect square. Thus, the equation is then x2 + 4x + 4 and the factor of it would bew (x+2)(x+2).

Answer: 1 unit tile is needed.

Step-by-step explanation:

In the question "How many unit tiles need to be added to the expression x2 + 4x + 3 in order to form a perfect square trinomial" the correct answer is 1 unit tile.

Because, to make the expression x^2 + 4x + 3 a perfecr square trinomial we have x^2 + 4x + 3 + 1 = x^2 + 4x + 4 = (x + 2)^2
