Answer:
Solving the equation for all real solutions in simplest form.
we get 
Step-by-step explanation:
We need to solve the equation for all real solutions in simplest form.

First simplifying the equation:

Now, we can solve the equation using quadratic formula:

we have a = 1, b=-12 and c=12
Putting values in formula and finding values of x

So, we get value of z: z=10.9 or z=1.1
Solving the equation for all real solutions in simplest form.
we get
