3 Options: if this is intentded to be 2x%5E2%2B4x%2B2=0
Option 1. Use the Quadratic Formula
Option 2. Divide the entire equation by 2 and find factors
Option 3. After option 2, complete the square
...
Option 1
x = %28-4+%2B-sqrt%284%5E2-4%282%29%282%29%29%29%2F%282%2A2%29
x = %28-4+%2B-sqrt%2816-16%29%29%2F4
x = %28-4+%2B-0%29%2F4
x = -1
...
Option 2
x%5E2+%2B+2x+%2B+1+=+0
(x+1)(x+1)=0
x+1=0
x = -1
...
Option 3
x%5E2+%2B+2x+%2B+%282%2F2%29%5E2%29=-1+%2B+%282%2F2%29%5E2
x%5E2+%2B+2x+%2B+1+=+-1+%2B+1
(x+1)^2 = 0
x = -1
