Question

2(m – 2)+3 (4m – 1) = 0​

Answer 1

Answer:

Step by step solution :

Step  1  :

Checking for a perfect cube :

1.1    m3-m2-4m+1  is not a perfect cube

Trying to factor by pulling out :

1.2      Factoring:  m3-m2-4m+1  

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1:  -4m+1  

Group 2:  m3-m2  

Pull out from each group separately :

Group 1:   (-4m+1) • (1) = (4m-1) • (-1)

Group 2:   (m-1) • (m2)

Bad news !! Factoring by pulling out fails :

The groups have no common factor and can not be added up to form a multiplication.

Answer 2

Answer:

2m-4+12m-3=0

14m-7=0

14m=7

m=1/2
