Step 1.1

Move the exponent $2$ from ${(x - 2)}^{2}$ outside the limit using the Limits Power Rule.

${(lim_{x \to 1^{+}} x - 2)}^{2}$

Step 1.2

Split the limit using the Sum of Limits Rule on the limit as $x$ approaches $1$ .

${(lim_{x \to 1^{+}} x - lim_{x \to 1^{+}} 2)}^{2}$

Step 1.3

Evaluate the limit of $2$ which is constant as $x$ approaches $1$ .

${(lim_{x \to 1^{+}} x - 1 \cdot 2)}^{2}$

Step 2

Evaluate the limit of $x$ by plugging in $1$ for $x$ .

${(1 - 1 \cdot 2)}^{2}$
