You would just have to isolate for x
so it would simply become
-1.56/-7.8
= 0.2
7/8= 0.875
no rounding necessary
A= -2
B= 4
C= -3
The equation the help you with this for later reference is **ax^2 + bx + c=0**
Answer:
c. 2b - 3
Step-by-step explanation:
Simplify the following:
-2 b + 4 + 4 b - 7
Grouping like terms, -2 b + 4 + 4 b - 7 = (4 b - 2 b) + (4 - 7):
(4 b - 2 b) + (4 - 7)
4 b - 2 b = 2 b:
2 b + (4 - 7)
4 - 7 = -3:
Answer: 2 b + -3
