2) a² + 7a + 6 = 0 → a² + 6a + a + 6 = (a + 6)(a + 1) → a = -6 or -1
3) b² + 4b + 4 = 0 → b² + 2b + 2b + 4 = (b + 2)(b + 2) → b = -2
4) c² + 5c + 6 = 0 → c² + 3c + 2c + 6 = (c + 3)(c + 2) → c = -3 or -2
5) d² + 8d + 12 = 0 → d² + 6d + 2d + 12 = (d + 6)(d + 2) → d = -6 or -2
6) e² + 6e + 8 = 0 → e² + 4e + 2e + 8 = (e + 4)(e + 2) → e = -4 or -2
7) f² + 7f + 10 = 0 → f² + 5f + 2f + 10 = (f + 5)(f + 2) → f = -5 or -2
8) g² + 8g + 7 = 0 → g² + 7g + g + 7 = (g + 7)(g + 1) → g = -7 or -1
9) h² + 10h + 9 = 0 → h² + 9h + h + 9 = (h + 9)(h + 1) → h = -9 or -1
10) i² + 8i + 16 = 0 → i² + 4i + 4i + 16 = (i + 4)(i + 4) → i = -4
11) j² + 7j + 12 = 0 → j² + 4j + 3j + 12 = (j + 4)(j + 3) → j = -4 or -3
12) k² + 10k + 16 = 0 → k² + 8k + 2k + 16 = (k + 8)(k + 2) → k = -8 or -2
13) m² + 8m + 15 = 0 → m² + 5m + 3m + 15 = (m + 5)(m + 3) → m = -5 or -3
14) n² + 12n + 20 = 0 → n² + 10n + 2n + 20 = (n + 10)(n + 2) → n = -10 or -2
15) p² + 9p + 18 = 0 → p² + 6p + 3p + 18 = (p + 6)(p + 3) → p = -6 or -3
16) q² + 12q + 32 = 0 → q² + 8q + 4q + 32 = (q + 8)(q + 4) → q = -8 or -4
