Question

Find the term that should be added to the expression to form a perfect square trinomial. Write the resulting perfect square trinomial in factored form. 
x^2+11x

anonymous · Answer

well, we have $(a+b)^2 = a^2 + 2ab + b^2$, so by analogy, what could $a$ and $b$ be?

anonymous · Answer

11/2)^@= 121/4= x^2+11x+121/4= (x+11/2)^2 but it's saying that's incorrect.

anonymous · Answer

That is undoubtedly a correct answer.  I am unsure why your book says otherwise.  Technically, you could also add on $-11x$, making for $(x+0)^2$.

anonymous · Answer

What is the constant term of the equation is the 121/ 4?

anonymous · Answer

Got it, it was. whoop.

anonymous · Answer

x^2 + 11x + 121/4
(x + 11/2)(x + 11/2)
that's ur answer :)
