Question

How do you find the roots, real and imaginary, of `y= 0.5x^2-0.6x +3.659` using the quadratic formula?

Answer 1

No real roots

Explanation:

`y = 0.5x^2 - 0.6x + 3.659 = 0`
`D = d^2 = b^2 - 4ac = 3.6 - 7.32 = - 3.72 < 0`.
Since D < 0, there are no real roots. There are 2 imaginary roots.
