(m + n)  ( m + n)

 

Multiply  the first term in the first set of parentheses over the two terms in the second set

 

m * m  + m * n

 

Multiply the second term in the first set of parentheses over the two terms in the second set

 

n * m  + n * n

 

Combine the results

 

m*m + m*n  + n*m + n*n  =

 

m^2  + 2mn + n^2
