Question 474903: I am home schooling my kids and cannot get my head around algebra
Can you please show me the setting out and answer to the following:
a) Remove grouping symbols:
m(m-4)
b) Remove grouping symbols and collect like terms:

If you are able to assist me in these answers then I can use these as examples for all the other sums.
Thanks heaps.

a) Remove grouping symbols:
m(m-4)
multiply each term in the Parenthesis by the m outside it
m*m-m*4
m^2-4m
b) Remove grouping symbols and collect like terms:
2(3m+1)-3(5-2m)
Similarly
2*3m+2*1 -3*5+(-3*-2m)
6m+2-15+6m
group the similar terms
6m+6m+2-15
12m -13
