Problem:Consider the quartic function  f \left(\right. x \left.\right) = \left(\right. x - a \left.\right) \left(\right. x - a \left.\right) \left(\right. x - b \left.\right) \left(\right. x - b \left.\right) - n such that a , \textrm{ } b , \textrm{ } n \in \mathbb{R} . Find the value of n, in terms of a and b, such that  f \left(\right. x \left.\right) has three distinct real zeros (two single roots and one double root).download document with problem and solution Quartic 3 Real Zeros with solution v2
