It shows combining and subtracting algebraic fractions, simplifying to a final rational expression, and then uses iterative formulas to approximate roots of cubics starting from specific guesses like x0 = -2.5 and x0 = 1.45. The video also covers relationships and checks for solutions using sign changes, midpoint and gradient calculations, solving equations by rearrangement and substitution, and algebraic proofs such as showing a difference between squares of consecutive odd numbers is a multiple of 8. Multiple numerical values are found along the way, including iterations converging to around -2.6 and solution estimates near 1.4496."}
