What is the factored form of this expression? x2 + 6x − 16

(x + 2)(x - 8)

Step-by-step explanation:

I did this by using the AC method. The AC method of factoring is basically a method to split the middle term bx into 2 separate terms so that you can eventually factor the trinomial using grouping. In order to split the middle term we will need to find the factors that make up the product of the coefficient A and C

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral

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.
