Answer: 10n4+7n3+3n
Step-by-step explanation:
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:
300
Step-by-step explanation:
Multiply the length which is 30 cm by 10 to give you the length in mm.
Answer:
6.58 x 10^1
Step-by-step explanation:
This is because the exponent 1 means that you have to move the decimal place in 6.58 to the right once which makes the standard form 65.8. And vice versa, if you move the decimal place to the left once in 65.8, then the answer is 6.58 x 10^1.
