3m -15m +12m
3 m - 12​

Answer 1

Step-by-step explanation:

2.2 Factoring m2 - m - 12

The first term is, m2 its coefficient is 1 .

The middle term is, -m its coefficient is -1 .

The last term, "the constant", is -12

Step-1 : Multiply the coefficient of the first term by the constant 1 • -12 = -12

Step-2 : Find two factors of -12 whose sum equals the coefficient of the middle term, which is -1 .

-12 + 1 = -11

-6 + 2 = -4

-4 + 3 = -1 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -4 and 3

m2 - 4m + 3m - 12

Step-4 : Add up the first 2 terms, pulling out like factors :

m • (m-4)

Add up the last 2 terms, pulling out common factors :

3 • (m-4)

Step-5 : Add up the four terms of step 4 :

(m+3) • (m-4)

Which is the desired factorization
