Question

Which graph represents the solution set for the quadratic inequality x² + 2x + 1 > 0?

Answer 1

Answer:

See attachment.

Step-by-step explanation:

The given inequality is $x^2+2x+1\:>\:0$

We can rewrite this inequality as  $(x+1)^2\:>\:0$

Or

$(x+1)(x+1)\:>\:0$

The solution to this inequality is {x<-1,x>-1}

The solution is all real numbers except -1

We can rewrite this as x≠-1
