Step-by-step explanation:
In choice a:
Both children between 5 and 15 years old and 160 years old are also the populations of interest, and Kids from 5 to 15 years of age.
In choice b:
These findings could be compared like we do not know whether the groups were randomly selected, and the allocation is still not random; there could be no casual conclusion because the statement is valid even With sample research, and after randomization, filtering, and testing of 160 specimens (instruction vs no-instruction) Its analysis can be common to the community and replicated. There could be explanatory relations generated by experimental research. This analysis is observational and can therefore be used Causal relationships are established.gggg

Since there's a common denominator, you can go straight into subtracting,
so for the top, x^2 + 8x - x^2 -2x + 6 will simplify to -6x -6 which with the bottom can be reduced (dividing everything by 3) to 2x - 2/x^2 + x
