Solve by factoring: one of the solutions to the quadratic equation x2 + 3x - 28 is x = -7. what is the other solution? (type only the numerical value of the other solution. do not use any variables or skip any spaces.) for the other solution, x = ? 19. solve by factoring: one of the solutions to the quadratic equation 2x2 - 7x + 5 is x = (5/2). what is the other solution? (type only the numerical value of the other solution. do not use any variables or skip any spaces.) the other solution is x = ?
