the first step is adding 40 to both sides of the equation

Step-by-step explanation:

Solving the quadratic equation means we solve the equation for x

To solve for x we need to isolate x^2

To isolate x^2, remove -40 from the left hand side

In order to remove -40 we do opposite operation

Opposite of -4 is +40

So we add 40 on both sides of the equation

the first step is adding 40 to both sides of the equation

adding 40 on both sides

Step-by-step explanation:

I definitely would not take the square root of both sides as my first step...

Adding 40 on both sides would give me x^2=40

That looks like an amazing first step because there is only one more thing after which is taking square root of both sides.

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 !
