How do you find the roots, real and imaginary, of #y= (x-3)^2+2x-5 # using the quadratic formula?
In order to use the quadratic equation, we must first get our equation to be in standard form. To do that, we need to simplify everything and then combine like-terms.
Now we just use the quadratic formula:
This seems to be the only root, but let's double check by graphing
Yep, our only root is at
