No, 4/5 does not equal to 5/10.
Because:- When you try to see if it is proportional, it does not equal it.
4/5 ≠ 5/10
Simplify to make sure.
4/5 ≠ 1/2
4/5 is NOT equal to 1/2.
Therefore, our final answer is that 4/5 does not equal 5/10.
Answer:
Option B 3,-3,-6 is correct.
Step-by-step explanation:
We need to find real zeroes of 
Solving

Taking x^2 common from first 2 terms and -9 from last two terms we get

Taking (x+6) common

x^2-9 can be solved using formula a^2-b^2 = (a+b)(a-b)

Putting it equal to zero,

So, Option B 3,-3,-6 is correct.
