Step-by-step explanation:

5) d² + 9d + 14

   d² + 7d + 2d + 14

   d(d + 7) + 2(d + 7)

   (d + 2)(d + 7)

6) x² + 8x - 9

   x² + 9x - x - 9

   x(x + 9) - 1(x + 9)

   (x - 1)(x + 9)

7) x² - 16

  (x)² - (4)²

  (x + 4)(x - 4)

8) sign missing cant tell answer...

9) p² -2p - 3

   p² -3p + p - 3

   p(p - 3) + 1(p - 3)

   (p + 1)(p - 3)

10) q² - 11q + 24

     q² - 8q - 3q + 24

     q(q - 8) - 3(q - 8)

     (q - 8)(q - 3)

11) p² - 2p - 3

    p² - 3p + p - 3

    p(p - 3) + 1(p - 3)

    (p + 1)(p - 3)

12) a² + 8a + 16

     a² + 4a + 4a + 16

     a(a + 4) + 4(a + 4)

     (a + 4)(a + 4)

     (a + 4)²

There you go.. Hope it helps :D

Thanks for 2K!
