How do you find the zeros, real and imaginary, of #y= -x^2-2x-1 # using the quadratic formula?
There are a double rooth, x = - 1.
Applying the Quadratic Formula, we can obtain the rooth of:
solving the equation:
Remember the Quadratic Formula:
Applying this formula to the equation given, we have:
Because the discriminant is zero, we have only one solution. In this case, the solution is real.
