A bacterial colony is estimated to have a population of
P(t) = 14t+4/t^2+1 million t hours after the introduction of a toxin.
At what time does the population begin to decrease.
Could someone please help me finish this problem:
p(t)= (t^2+1) x 14 - (14t+4) x 2t = -14t^2-8t+14 / (t^2+1)
To find out when the population begins to decrease, what is my next step? My book explains that the next step is to factor the numerator which in this case could factor out to be -2(7t^2+4t-7)(?).
Well that is about how far I get, I can't seem to figure out how to factor out this problem I guess.
help please and thankyou!
