That doesn't factor neatly. Applying the quadratic formula, we find two real solutions: (4 plus or minus the square root of 10) divided by 3
x = 2.3874258867227933
x = 0.2792407799438735
x2 + 3x + 2 factors into (x + 1) (x + 2)
That factors to (2n + 1)(n + 2)
2 and 4x + 1
That factors to (x + 5)(3x + 2)
x^3+x^2+2x = x(x^2+x+2)
2(x + 13)
-((x + 2)(x - 8))
-2 and -6
Divide all terms by 2 and when factored it is: (x+1)(x+1)
1, 5, 13 and 65
8a times (2 + 1)
14x(x + 2)
