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-4 is the correct answer for Apex
(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)
X^2 - 13X + 30 = 0 (X-3)(X-10) easy inspection problem
