Hi Clint;
x^{2}+1=2x+1
Let's move everything to one side by subtracting (2x+1) from both sides...
(x^{2}+1)(2x+1)=(2x+1)(2x+1)
(x^{2}+1)(2x+1)=0
Let's eliminate 11...
x^{2}2x=0
Let's factor...
(x2)(x+0)=0
Let's FOIL...
FIRST...(x)(x)=x^{2}
OUTER...(x)(0)=0
INNER...(2)(x)=2x
LAST...(2)(0)=0
x2=0
and
x+0=0
x=0 and 2
