I am not pretty sure but this one looks pretty close to the question!
D. 4x^2 - 3 is the correct answer. This is because we just break the original expression down into two fractions and then simplify them
(8x^3 - 6x)/2x becomes these two fractions:
8x^3/2x - 6x/2x
These two simplify down to your answer, 4x^2 - 3
Answer:
YES, the positive feedback leads to the instability and the negative feedback leads to the stability.
Explanation:
- The melting of the glacier ice is an example of the negative feedback as it being a balance in the amount of the ice and the temperature extremes and therefore is a proper way to check the ice cover and thus he arctic ocean will be balanced by the absorption of the sun heat and the leads to the reduction in the temperatures in the nearby lands. And it's a natural cyclic system of the earth.
