Which value must be added to the expression x^2+12x to make it a perfect square trinomial a:6 b:36 c:72 d:144
Ksivusya [100]

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:
