Answer:
1. -8x² - 16x - 6 a = -8, b = -16, c = -6
1. 4x² - 1 a = 4, b = 0, c = -1
Step-by-step explanation:
use the 'foil' method:
(4x + 2)(-2x - 3)
F: -8x² O: -12x I: -4x L: -6
-8x² - 16x - 6
(2x + 1)(2x - 1)
F: 4x² O: -2x I: 2x L: -1
4x² - 1

1) 0,4
2) 0,3/5
3) -6,6
4) -9/4, 9/4
5) -6+3√7, -6-3√7
6) 11,7
7) 6,-5
8) 5, -12
9) 10
10) -1/5,-2
11) -5/4, 3/2
12) -1/4, 8/3
13) -5, -6
14) -9, 1
15) 3,2
16) 8
17) 6,-4
18) 0,4
19) 7,5 (factored) 6,-1 (vertex)
The vertex form let’s you find the vertex. The factored form gives you the roots.
