This topic focuses on rational function inequalities involving factored quadratics over binomials. It explores the concept of sign changes at points where the values of the variable lead to zero in the denominator or result in changes in the overall sign of the rational expression. This involves examining critical points where the numerator or denominator might equal zero and determining whether this influences the positivity or negativity of the function's value around those points.
