Question 91812
The solution for multiplication of 2 polynomials using Vertical method is done as folows: 


{{{(m^2 - 5mn + 3n^2)}}}
{{{(m^2 + 4mn - 2n^2)}}}  multiplying term by term
----------------------------------
              {{{(2m^2n^2 + 10mn^3 - 6n^4)}}}
      {{{(4m^3n - 20m^2n^2 + 12mn^3)}}} 
{{{(m^4 - 5m^3n + 3m^2n^2)}}} 
------------------------------------   Adding Like terms, we get: 
{{{(m^4 - m^3n - 15m^2n^2 + 22mn^3 - 6n^4)}}} 


Hence, the solution.
