Answer:
A
Step-by-step explanation:
Hello there!
To find the zeroes or the roots of a function, you just need to set the function equal to 0 then solve for x
f(x) = 2x² - 8x - 10
Set function equal to 0
2x² - 8x - 10 = 0
Now we can factorize the left side
2(x + 1)(x - 5) = 0
Then set factors equal to 0
x + 1 = 0 or x - 5 = 0
x = 0 - 1 or x = 0 + 5
x = -1 or x = 5
Thus,
The roots are -1 and 5

Answer: A. its basically symmetry
B. I don't know
Step-by-step explanation:
Answer:
c=4
Step-by-step explanation:
-5c - 15 = -35
Add 15 to each side
-5c - 15+15 = -35+15
-5c = -20
Divide each side by -5
-5c/-5 = -20/-5
c = 4
