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
