Answer:

y was not substituted for every x

Step-by-step explanation:

To find the inverse of ...

y = f(x)

you need to solve ...

x = f(y)

Here, f(x) = x^2 +12x, so f(y) = y^2 +12y

This is not the expression we see on the right of ...

x = y^2 +12x

Apparently y was not properly substituted into f(x).
