The answer would be 36. Why?


Because in the equation we would need to do (x + 6)(x + 6) to get a perfect square trinomial.


And 6 * 6 is 36.


So the whole equation would be: x^2 + 12 + 36.


Hope this helped! c:

The quadratic expression uses the following formula:


[tex] ax^2 + bx + c [/tex]


The expression is missing the variable of c, and it is a perfect square trinomial.


To find c in a perfect square trinomial, we will use the following formula:


[tex] c = (\frac{b}{2}})^2 [/tex]


The value of b in this expression is 12. Plug this value into the formula:


[tex] \frac{12}{2} = 6 [/tex]


[tex] 6^2 = \boxed{36} [/tex]


36 must be added to make this trinomial a perfect square.
