x2 + 13x + 4 = (x + 6½ + √38¼)(x + 6½ - √38¼).
To find this, we need to find p and q, where
p + q = 13, pq = 4.
4 = 42¼ - 38¼
= (6½ + √38¼)(6½ - √38¼); thus,
p = (6½ + √38¼), q = (6½ - √38¼).

(x + 10)(x + 3)
6x2 + 13x + 2 = (6x + 1)(x + 2).
(x - 5)(x - 8)
(x - 9)(x - 4)

x-4 is the correct answer for Apex
(x + 10)(x + 3)
(x - 10)(x - 3)
(5x - 4)(3x + 5)
6x2 + 13x + 2 = (6x + 1)(x + 2).
(5x - 4)(3x + 5)
(x - 6)(x - 7)
(x + 5)(x + 8)
x2 - 13x + 30 = (x - 3)(x - 10). In case you are provided with a list that you forgot to include with your question, then any of the following is a possible factor: x - 3; x - 10; 3 - x; or 10 - x.
