How do you find the zeros, real and imaginary, of #y=-x^2- x -35# using the quadratic formula?
The zeros are
The zeros are the solution of this equations
first of all we can remove all the minus multiplying left and right for
The quadratic formula tells us that an equation in the form
We notice that the root is negative and then imaginary. So I rewrite it using the fact that
The two solutions are then
