Solve the following equations. Be sure to check your answers for any extraneous solutions. Homework Help ✎

  1. You can solve this graphically or algebraically. For either method, it will simplify the task if you add x to both sides first.

    2x − 1 = (x − 8)2

    2x − 1 = x2 − 16x + 64

    0 = x2 − 18x + 65

    You can use the Zero Product Property to solve.

  2. Use one of the methods mentioned in part (a).

    x = 1
