Given the following quadratic equation, what is the value of A? 5x^2+8x-4

*5
*2
*8
*4

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

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2
