Find all real solutions of the equation. Make sure to simplify your solutions. If one or more of your solutions is not an integer, then write it as a decimal rounded to 1 decimal place. List your solutions from smallest to largest. For example: -7.2 0 1 10 I've left 4 spaces for the solutions. If the equation has less than 4 solutions, enter DNE in the remaining empty boxes.
