How do you find the roots, real and imaginary, of #y=(x – 7 )^2# using the quadratic formula?
First off, we really don't need the quadratic formula to find all the roots here since it's already factored, but I'll use it anyway.
We need your equation in standard form to use the QF. I'm assuming you know how to do this.
Now, just apply the QF
That's the only root it has. There are no imaginary roots for this quadratic.
