Really need your help on this question.

Numerator 2b^2 + 2a^2

Denominator (b-a)(b+a)^2

Step by step explanation :

2b / (b+a)^2 + 2a / (b-a)(b+a)

2b (b-a) + 2a (b + a) / (b-a) * (b+a)^2

2b^2 - 2ab + 2ab + 2a^2 / (b-a)(b+a)^2

2b^2 + 2a^2 / (b-a) * (b+a)^2

the answers are in the images, i received 100% on this assignment. hope this !

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
