Answer:
A)
Step-by-step explanation:
the solution of a squared equation is
x = (-b ± sqrt(b² - 4ac)) / (2a)
in our case
a = 1
b = 8
c = 22
x = (-8 ± sqrt(64 - 88))/2 = (-8 ± sqrt(-24))/2 =
 = (-8 ± sqrt(4×-6))/2 = (-8 ± 2×sqrt(-6))/2 =
 = -4 ± sqrt(-6) = -4 ± i×sqrt(6)
 
        
             
        
        
        
20% because 75 is the total price and 75 over 15 is 5 and 100 divided by 5 is 20
        
             
        
        
        
Answer:
a(a - b)
Step-by-step explanation:
<u>given </u><u>polynomial</u>:  a²- ab - 8a + 8a
We can first simplify this answer by removing like terms,
- 8a + 8a = 0
so we have a²- ab in. the simplest form
we can take this one step further and factor out the a (not simplest form)
a time a = a²
a times b = ab
hence, a(a - b)
