Answer 1

To solve the quadratic equation \((x+36)^2 - 38 = 251\) using square roots, we can follow these steps:

1. Isolate the square: \[ (x+36)^2 - 38 = 251 \] Add 38 to both sides: \[ (x+36)^2 = 251 + 38 \] \[ (x+36)^2 = 289 \]

2. Take the square root of both sides: \[ x + 36 = \pm \sqrt{289} \] Since \(\sqrt{289} = 17\): \[ x + 36 = \pm 17 \]

3. Solve for \(x\):

   • For the positive case: \[ x + 36 = 17 \implies x = 17 - 36 \implies x = -19 \]
   • For the negative case: \[ x + 36 = -17 \implies x = -17 - 36 \implies x = -53 \]

Thus, the solutions are \(x = -19\) and \(x = -53\).

The correct response is:

\({-19, -53}\)
