Answer:
Step-by-step explanation:
Given expression is,
f(x) = 8x³ - 6x² - 36x + 27
For zeros of the function,
f(x) = 0
8x³ - 6x² - 36x + 27 = 0
2x²(4x - 3) - 9(4x - 3) = 0
(2x² - 9)(4x - 3) = 0
(2x² - 9) = 0
x² = 
x = 
x = 
Or (4x - 3) = 0
x = 
Therefore, all zeros of the given functions are .
Answer:
D) -6
Step-by-step explanation:
Answer:
z=3
Step-by-step explanation:
Add 3z and 2z
5z-5=25-5z
Add 5z on both sides to eliminate the -5z on the RHS
10z-5=25
Add 5 on both sides to eliminate the -5 on the LHS
10z=30
Divide by 10
z=3
Hope this helps!
a. -42 + (-17)
Note that one negative and one positive = negative
-42 + (-17) = -42 - 17 = -59
b. (-42)/(-7)
Note that when dividing or multiplying two negatives, the answer will be positive
(-42)/(-7) = 6
c. (-5)² = (-5)(-5) = 25
25 is your answer
hope this helps
