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 . <u>**(m - 10) and (m - 2) are your two factors.**</u>

**Step-by-step explanation:**

**Answer:**
