Factor (x + 2) 2 - (y - 2) 2.

2 (x-y+4)

Step-by-step explanation:

Step 1:

Equation at the end of step 1:

((x + 2) • 2) - 2 • (y - 2)

Step 2:

Equation at the end of step 2:

2 • (x + 2) - 2 • (y - 2)

Step 3:

Pulling out like terms:

3.1 Pull out 2

After pulling out, we are left with:

2 • (1 * (x+2) + ((-1) * (y-2)))

Final result:

2 • (x - y + 4)
