Aquadratic equation is shown below: 3x2 − 15x + 20 = 0 part a: describe the solution(s) to the equation by just determining the radicand. show your work. (5 points) part b: solve 3x2 + 5x − 8 = 0 by using an appropriate method. show the steps of your work, and explain why you chose the method used. (5 points)

Step-by-step explanation:

a=3, b=-15, c=20

Discriminant can be calculated as

The roots are imaginary

The solution is

The roots are not real i.e these are imaginary    

a=3, b=5, c=-8

Discriminant can be calculated as

The roots are real

By quadratic formula method

The solution is

which are required roots.

I choose this method because I can get the solutions directly by substituting the values in formula, and I don't have to guess the possible solutions.

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
