( | x | + | 1 | ) | + | 1 | ÷ | ( | x | + | 1 | ) | = | 0 |
Multiply both sides of the equation by: | ( | x | + | 1 | ) |
( | x | + | 1 | ) | ( | x | + | 1 | ) | + | 1 | = | 0 |
x | ( | x | + | 1 | ) | + | 1 | ( | x | + | 1 | ) | + | 1 | = | 0 |
x | x | + | x | × | 1 | + | 1 | ( | x | + | 1 | ) | + | 1 | = | 0 |
x | x | + | 1 | x | + | 1 | x | + | 1 | × | 1 | + | 1 | = | 0 |
x | x | + | 1 | x | + | 1 | x | + | 1 | + | 1 | = | 0 |
x | x | + | 2 | x | + | 2 | = | 0 |
