How do you find the roots, real and imaginary, of #y= x- (x-2)(x-1) # using the quadratic formula?
To write the quadratic formula, your equation first needs to be in standard form:
In order to get this, just simplify your equation.
Now you can look turn this into the quadratic formula:
The variables in standard form are the same as the ones in the quadratic formula, which means you can easily transfer them over.
All you have to do is plug in and solve!
You should get two real roots as your answer:
