The document discusses three methods for finding the roots of equations: 1) The graphic method involves plotting the equations on a graph to find the point where they intersect, representing the root. It can determine if a system is compatible, incompatible, or has infinite solutions. 2) The bisection method iteratively narrows down the interval containing the root by dividing it in half. 3) The false position method uses the slopes of lines through two initial points to estimate a new test point, converging faster than bisection by incorporating information about the function.
