1. The problem statement, all variables and given/known data Consider the fourth order equation x4 + 5x2 + 6 = 0. (a) Suggest an efficient way to find all roots of this equation. (b) List all the roots. 2. Relevant equations 3. The attempt at a solution -I plotted the graph. -I thought of iteration - Is that correct ? For that I have to change the form of the equation but then it is not given - Usually for iteration, they mention. -I thought of first derivative but what use is it going to be ?
