Solve the quadratic equation using square roots (x+6)^2 /2 =8

1 answer

To solve the equation \(\frac{(x + 6)^2}{2} = 8\), we can follow these steps:

  1. Eliminate the fraction by multiplying both sides by 2:

    \[ (x + 6)^2 = 16 \]

  2. Take the square root of both sides, remembering to consider both the positive and negative roots:

    \[ x + 6 = 4 \quad \text{or} \quad x + 6 = -4 \]

  3. Solve for \(x\) in each case:

    • For the first case: \[ x + 6 = 4 \implies x = 4 - 6 \implies x = -2 \]

    • For the second case: \[ x + 6 = -4 \implies x = -4 - 6 \implies x = -10 \]

  4. Write the solutions:

    The solutions to the equation \(\frac{(x + 6)^2}{2} = 8\) are: \[ x = -2 \quad \text{and} \quad x = -10 \]
