simplify (x^2+2x+1)/(x+1)
The original denominators must be nonzero: x ≠ -1
Let's reduce: x2 + 2x + 1x + 1
Let's factorize in ℝ: x2 + 2x + 1
You can transform this expression into: (x + 1)2
The fraction: (x + 1)2x + 1 simplifies by the common factor: x + 1 into the new expression: x + 1
▶Simplified form:   x + 1
