Reformatting the input :

Changes made to your input should not affect the solution:

 (1): "o4"   was replaced by   "o^4".  1 more similar replacement(s).

Step  1  :

Equation at the end of step  1  :

  mas2 -  3asl2o4

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   mas² - 3asl²o⁴  =   as • (ms - 3l²o⁴) 

Trying to factor as a Difference of Squares :

 3.2      Factoring:  ms - 3l²o⁴ 

Theory : A difference of two perfect squares,  A² - B²  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =
         A² - AB + BA - B² =
         A² - AB + AB - B² =
         A² - B²

Note :  AB = BA is the commutative property of multiplication.

Note :  - AB + AB equals zero and is therefore eliminated from the expression.

Check : 3 is not a square !!

Ruling : Binomial can not be factored as the difference of two perfect squares.

Final result :

  as • (ms - 3l2o4)
