Aʙᴏᴜᴛ Tʜɪs Vɪᴅᴇᴏ – This video looks at supporting a method to find a cubic equation with unknown coefficients and known complex roots. By setting up an equation which involves a quadratic and using support from the calculator we are able to find the quadratic that gives the complex roots. Following that polynomial multiplication can get us back to the original cubic equation. We can then use the calculator again to verify our result.
