Answer

The solutions are \(x = -\sqrt{19} + 11\) and \(x = \sqrt{19} + 11\).

Solution

Solve the equation \( (x-11)^{2}=19 \). Solve the quadratic equation by following steps: - step0: Solve using square roots: \(\left(x-11\right)^{2}=19\) - step1: Simplify the expression: \(x-11=\pm \sqrt{19}\) - step2: Separate into possible cases: \(\begin{align}&x-11=\sqrt{19}\\&x-11=-\sqrt{19}\end{align}\) - step3: Move the constant to the right side: \(\begin{align}&x=\sqrt{19}+11\\&x=-\sqrt{19}+11\end{align}\) - step4: Rewrite: \(x_{1}=-\sqrt{19}+11,x_{2}=\sqrt{19}+11\) The solution set for the equation \((x-11)^{2}=19\) using the square root property is \(x = -\sqrt{19} + 11\) or \(x = \sqrt{19} + 11\).

To solve the equation \( (x - 11)^{2} = 19 \) using the square root property, we first take the square root of both sides. This gives us: \[ x - 11 = \pm \sqrt{19} \] Now, we isolate \( x \) by adding \( 11 \) to both sides: \[ x = 11 \pm \sqrt{19} \] Thus, the solution set is \[ \left\{ 11 + \sqrt{19}, 11 - \sqrt{19} \right\} \]
