Respuesta :

product means multiplication and a sum means addition, so the final form will look like this:

a*(b+c)

a will be 2: 1+4+1+4 can be rewritten as (1+4)+(1+4)= we see that (1+4) is there twice: so that's where the 2 comes from. 

and the b+c will be 1+4

so the result is 2*(1+4)

factor 1: 2
factor 2: (1+4)
