Answer:
See below
Step-by-step explanation:
I'll provide an example to help you. Let's say we were solving 
and we wanted to factor the quadratic on the left side. We can't do that because the factors of -7 don't add up to 5. So we'd have to use the quadratic formula. The quadratic formula is essentially the last resort that will solve all quadratic equations, so it could be seen as a preferred method. But, unless you can factor the quadratic, it's much easier to solve.
Now let's do another one. 
for example can be written as 
and we can easily get 
and 
as solutions since plugging them into the factors would produce 0 (from the Zero Product Property). If we used the quadratic formula, it would take more time to plug in the variables and solve when we can just simply factor.
Hopefully, this explanation helps you to think of your discussion post!
Answer:
Well since land is a solid. NO, he can't swim on land.

Answer:
Step-by-step explanation:
The sum of two irrational numbers is always still irrational.
5√3 + 6√5 is still going to be irrational. You cannot find two such numbers adding to rational.
Rt-2n=y -- add 2n
Rt=y+2n -- divide by R
t=(y+2n)/R
Answer: The answer would be the first choice.
Step-by-step explanation:
Remember that a function is where every INPUT has exactly ONE OUTPUT. That means for the coordinates (x, y), no pair could have an x value repeat. So, the first ordered row pair does not have any repeating x values, so it's the first answer.
