Answer:The roots of any quadratic equation is given by: x = [-b + / - sqrt (-b^2 - 4ac) ]/2a. Write down the quadratic in the form of ax^2 + bx + c = 0. If the equation is in the form y = ax^2 + bx + c, simply replace the y with 0. This is done because the roots of the equation are the values where the y axis is equal to 0.
