Well threw my calculations would be <span><span> x= 0.0000 - 2.0000 i
</span><span> x= 0.0000 + 2.0000 i
</span></span>
The way to do is is to write down expression, find factors of each polynomial and than cancel as many as possible. What remains is our simplified version of starting expression.
We start with this:
Now we factor every polynomial
now we can cancel fallowing factors:
5x-3, x-1 and x+5
after that we left with:
The percent is 85.71% so the rounded answer would be be 86%
25 million
number of bacteria doubles every minute
Definitely not D, because one of the x's needs to be negative, and the other should be positive so the x will end up negative when it is multiplied.
I want to say the answer is C. (-x-2i) (x-2i)
Hope this helps :)
