Answer:
Step-by-step explanation:
1. x^2 + 6x = 5
x^2 + 6x + 9 = 14
(x+3)^2 = 14
x =
- 3
2. x^2 + 8x -4 = 0
x^2 + 8x = 4
x^2 + 8x + 16 = 20
(x+4)^2 = 20
x =
- 4
Answer:
(I am assuming that you don't need the answer, but just an explanation of what to do.) Let's take the first problem for an example the first thing you are going to do is subtract 12 on both sides and you will get n> -1 so then you will put a open circle on -1 going to the right.
