    That makes no sense. You are given the equation. Perhaps find the solutions?

    It's just a quadratic equation. Have you solved any of those?

    Yup. Solve the equation for x. You are given the equation. Your task is to find a value for x that satisfies the equation. 1^2 = 1 2^2 = 4 3^2 = 9 4^2 = 16 5^2 = 25 6^2 = 36 ... 10^2 = 100 ... 15^2 = 225 Are we getting close?

    Exactly. So,I must have missed it. Can you find the right value?

    Ohh so it would be 14 to the power of 2 right

    \[x^2=196\\ x\times x = 196\\ x = \pm\sqrt{196}\]

    It seemed to me that we were not worried about that other solution, based on the visual observation of the problem statement. We certainly aren't going to expect a student at this level to find all three solutions to the next problem.
