You should perform the following steps when you need to solve the quadratic equation `ax^2 + bx + c = 0` , such that:

- identification of values of coefficients a,b,c

- check if `Delta = b^2 - 4ac >= 0` or `Delta < 0` to determine if the roots `x_1` and `x_2` are real or complex conjugate

- substitution of the values of coefficients a,b,c in quadratic formula `x_(1,2) = (-b+-sqrtDelta)/(2a) `

**Hence, performing the steps above, you may evaluate the roots of quadratic equation `ax^2 + bx + c = 0, x_(1,2) = (-b+-sqrt(b^2-4ac))/(2a).` **
