1. Substitute $$ x=5 $$ into the expression:
   
   $$
   5^{2} + 8(5) - 12
   $$

2. Calculate $$ 5^{2} $$:
   
   $$
   5^{2} = 25
   $$

3. Calculate $$ 8(5) $$:
   
   $$
   8(5) = 40
   $$

4. Substitute the calculated values back into the expression:
   
   $$
   25 + 40 - 12
   $$

5. Add and subtract to find the result:
   
   $$
   25 + 40 = 65
   $$
   
   $$
   65 - 12 = 53
   $$

The value of the expression is $$ 53 $$.
When $$ x=5 $$, the expression $$ x^{2}+8x-12 $$ equals 53.

If \( x=5 \), evaluate the value of this expression: \[ x^{2}+8 x-12 \]
