Select all the correct answers. Use the graphing tool to find the roots of the quadratic equation you derived from the original rational equation in part B: x2 − 5x − 6 = 0. To use graphing to solve the equation, set the equation equal to 0, and replace the 0 with y. So, input this equation: y = x2 − 5x – 6. Observe the graph, and select the root(s) of the equation.
