Factor the quadratic expression 3x^2 + 4x - 4*

(x+2)(3x-2)

Step-by-step explanation:

3x^2 +4x-4

AC method

_×_= ac=-12

_+_=b = 4

6 and -2

But because a is multiplied by 3 you need to divide both by 3 so 6/3 is 2 and because you can not divide -2 by three you move the 3 back to the x and leave it as (3x-2)

i will pick c put check it over to be sure

step-by-step explanation:

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.
