Identify the two solutions to the quadratic equation. (1 point) The smaller of the two solutions is x=x=. The larger of the two solutions is x=x=.

3 answers

To solve the equation \((x - 7)^2 = 11\), we first need to isolate \(x\).

  1. Take the square root of both sides: \[ x - 7 = \pm \sqrt{11} \]

  2. Solve for \(x\): \[ x = 7 + \sqrt{11} \quad \text{or} \quad x = 7 - \sqrt{11} \]

Now, we need to evaluate and determine the approximate values of these solutions.

  • The approximate value of \(\sqrt{11}\) is about \(3.3166\).

Thus, the solutions become:

  1. \(x = 7 + \sqrt{11} \approx 7 + 3.3166 = 10.3166\)
  2. \(x = 7 - \sqrt{11} \approx 7 - 3.3166 = 3.6834\)

Now, identify the two solutions:

  • The smaller of the two solutions is: \[ x \approx 7 - \sqrt{11} \implies x \approx 3.6834 \]
  • The larger of the two solutions is: \[ x \approx 7 + \sqrt{11} \implies x \approx 10.3166 \]

Answers:

  • The smaller of the two solutions is \(x \approx 3.6834\).
  • The larger of the two solutions is \(x \approx 10.3166\).
wrong

Let’s carefully solve the equation \((x - 7)^2 = 11\) step-by-step to find the solutions correctly.

  1. Rewrite the equation: \[ (x - 7)^2 = 11 \]

  2. Take the square root of both sides: \[ x - 7 = \pm \sqrt{11} \]

  3. Solve for \(x\):

    • For the positive square root: \[ x = 7 + \sqrt{11} \]
    • For the negative square root: \[ x = 7 - \sqrt{11} \]
  4. Now let's calculate the approximate numerical values:

    • The approximate value of \(\sqrt{11}\) is about \(3.3166\).
    • Calculating the two solutions:
      • Larger solution: \[ x = 7 + \sqrt{11} \approx 7 + 3.3166 \approx 10.3166 \]
      • Smaller solution: \[ x = 7 - \sqrt{11} \approx 7 - 3.3166 \approx 3.6834 \]

Final Answers:

  • The smaller of the two solutions is \(x \approx 3.6834\).
  • The larger of the two solutions is \(x \approx 10.3166\).

These calculations are correct. If you have other specific values you want me to evaluate from a table you haven't provided, please share those, and I can evaluate them for you.
