Answer 1

To solve the equation \((x+36)^2 - 38 = 251\), we first simplify it step by step.

1. 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 \(x + 36 = 17\): \[ x = 17 - 36 = -19 \]
   • For \(x + 36 = -17\): \[ x = -17 - 36 = -53 \]

So the two solutions are: \[ x = -19 \quad \text{and} \quad x = -53 \]

Thus, the solution set is: \[ {-19, -53} \]

The correct response is: \({−19,−53}\)
