Write the quadratic equation in standard form.

Step-by-step explanation: If we want to put this in standard form, we first want to add 2x² to both sides of the equation to get 2x² + 5x - 17 = 0.

Notice that I have set up the left side of the equation in descending order of powers. In other words, first the x² term, then the x term, then the constant term.

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.
