average of 4 numbers is 11 so 11*4 = 44

Suppose you want to factor the expression x2+ 2xn+n2. Given that n&gt; 0, what are the factors? Explain.
spin [16.1K]

Answer:

(x + n)^2

Step-by-step explanation:

Okay! Let's get this going!

(x + n ) ^2 is correct because first we get

x^2 and n^2. Yet we need to add one more part to this to make it true which is x * n. We multiply this by two since according to the formula (a + b)^2 = a^2 + 2ab + b^2
