Answer:
\begin{gathered} Simplest\text{ form: }(x+2)/(x-7) \\ \\ Restriction:\text{ x ^^^^2260 7} \end{gathered}Step-by-step explanation:

The given expression is:


(x^2+4x+4)/(x^2-5x-14)

Factorize the numerator


\begin{gathered} x^2+4x+4 \\ \\ x^2+2x+2x+4 \\ \\ x(x+2)+2(x+2) \\ \\ (x+2)(x+2) \end{gathered}

Factorize the denominator


\begin{gathered} x^2-5x-14 \\ \\ x^2-7x+2x-14 \\ \\ x(x-7)+2(x-7) \\ \\ (x+2)(x-7) \end{gathered}

The given quotient expression then becomes:


\begin{gathered} ((x+2)(x+2))/((x+2)(x-7)) \\ \\ (x+2)/(x-7) \end{gathered}

The simplest form is:


(x+2)/(x-7)

The restriction is:

x ≠ 7
