The factors of 2 are 1 and 2
Also, 1 + 2 = 3
%28x+%2B+2%29%28x+%2B+1%29+=+x%5E2+%2B+3x+%2B+2
%28x+%2B+2%29%28x+%2B+1%29+=+0
If x+=+-2, the equation is solved
-2+%2B+2%29%28-2+%2B+1%29+=+0
0%2A%28-1%29+=+0
0+=+0
Also, if x+=+-1, the equation is solved
%28-1+%2B+2%29%28-1+%2B+1%29+=+0
1%2A0+=+0
0+=+0
x+=+-1 and x+=+-2 are the solutions
