To find the lengths of the two pieces of wire, we need to set up a simple equation. Let's call the length of the shorter piece x.

According to the given information, the longer piece is 2 feet longer than the shorter piece. So, the length of the longer piece would be x + 2.

We know that the electrician cuts a 14 ft piece of wire into the two pieces. Therefore, the equation we can form is:

x + (x + 2) = 14

Now, we can solve this equation to find the value of x, which will give us the length of the shorter piece. Then, we can substitute this value back into the equation to find the length of the longer piece.

x + x + 2 = 14
2x + 2 = 14
2x = 14 - 2
2x = 12
x = 12 / 2
x = 6

So, the length of the shorter piece is 6 ft. To find the length of the longer piece, we substitute the value of x into the equation x + 2:

6 + 2 = 8

Therefore, the lengths of the two pieces are 6 ft and 8 ft, respectively.
