Suppose the equation ax^2+bx+c=0 has no real solution and a graph of the related function has a vertex that lies in the second quadrant. is the value of "a" positive or negative? explain your reasoning. suppose the graph is translated so the vertex is in the fourth quadrant. does the graph have any x-intercepts? explain.

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103
