To apply the quadratic formula, we need the equation in the form: ax^2 + bx + c = 0. We can re-write the given equation as: x^2 + 23x + 20 = 0. Now, applying the quadratic formula, we get:

x = (-b ± sqrt(b^2 - 4ac)) / 2a 
x = (-23 ± sqrt(23^2 - 4(1)(20))) / 2(1) 
x = (-23 ± sqrt(289)) / 2 
x = (-23 ± 17) / 2

Therefore, the roots are x = -3 and x = -20. None of the answer choices match the roots, but choice C matches the coefficients in the equation.
