What are the factors of m2 – 12m + 20? m – 14 and m – 6m – 10 and m – 2?

its B

Step-by-step explanation:

So for this polynomial, we will be completing the square. Firstly, what two terms have a product of 20m^2 and a sum of -12m? That would be -10m and -2m. Replace -12m with -2m - 10m:

Next, factor m^2 - 2m and -10m + 20 separately. Make sure that they have the same quantity inside of the parentheses:

Now you can rewrite this expression as . (m - 10) and (m - 2) are your two factors.

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
