WebOct 19, 2024 · The axis of symmetry is the real part of the complex roots; the imaginary part can be found by subtracting the square of the axis (here, $4$) from the intercept ($13-4=9$) and then taking the square root ($3$). This assumes the roots come in conjugate pairs (so the coefficients of your quadratic are real numbers). $\endgroup$ – Webbuffalo airways fatal crash; find caste by surname in andhra pradesh. lone wolf ashes elden ring: how to use; shooting in warrensville heights last night
