1^2 + 1^2 + 1^2 + 1^2 + 1^2 + 1^2 = 1 + 1 + 1 + 1 + 1 + 1 = 5
x2 + 4x + 3 =(x + 3) (x + 1)
285
3(x + 4)(x + 1)
104
4x2 + 1 + x2 + 3 = 5x2 + 4
1^2 + 1^2 + 1^2 + 1^2 + 1^2 + 1^2 = 1 + 1 + 1 + 1 + 1 + 1 = 5
3(x2 + 3x + 1)
(4x + 1)(2x + 3)
3
3x2 + 10x + 3 = (x + 3)(3x + 1).
x2 + 4x + 3 =(x + 3) (x + 1)
The answer is (2x^2+3)(4x+1)

8x3 + 4x2 + 6x + 3 = 4x2(2x + 1) + 3(2x + 1) = (2x + 1)(4x2 + 3)
3(3n - 1)(n + 1)
