Question

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

Answer 1

Answer:

its B

Step-by-step explanation:

Answer 2

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: $m^2-2m-10m+20$

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

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