Question

simplify and give full explanation : m(3m + 1) - 4(3m +1) + m(2m - 1)​

Answer 1

Answer:

:D

Step-by-step explanation:

(m−2)(m−1)(m−3)

3m−9+2m−4−m+1

​

 

Combine 3m and 2m to get 5m.

(m−2)(m−1)(m−3)

5m−9−4−m+1

​

 

Subtract 4 from −9 to get −13.

(m−2)(m−1)(m−3)

5m−13−m+1

​

 

Combine 5m and −m to get 4m.

(m−2)(m−1)(m−3)

4m−13+1

​

 

Add −13 and 1 to get −12.

(m−2)(m−1)(m−3)

4m−12

​

 

Factor the expressions that are not already factored.

(m−3)(m−2)(m−1)

4(m−3)

​

 

Cancel out m−3 in both numerator and denominator.

(m−2)(m−1)

4

​

 

Expand the expression.

m  

2

−3m+2

4
