Answer:

5m2n • (3m2 + 2mn - 4n2)

explanation:

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "n3"   was replaced by   "n^3".  4 more similar replacement(s).

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 (((10•(m3))•(n2))+((15•(m4))•n))-((22•5m2)•n3)

Step  2  :

Equation at the end of step  2  :

 (((10•(m3))•(n2))+((3•5m4)•n))-(22•5m2n3)

Step  3  :

Equation at the end of step  3  :

 (((2•5m3) • n2) +  (3•5m4n)) -  (22•5m2n3)

Step  4  :

Pulling out like terms :

5.1     Pull out like factors :

  15m4n + 10m3n2 - 20m2n3  =   5m2n • (3m2 + 2mn - 4n2)  

Trying to factor a multi variable polynomial :

5.2    Factoring    3m2 + 2mn - 4n2  

Try to factor this multi-variable trinomial using trial and error  

Final result :

 5m2n • (3m2 + 2mn - 4n2)
