4(s+2)+s-1 simplify the equation

Sagot :

Firstly, the best thing to do is to expand the bracket.
To expand, you multiply everything at the front of the bracket by everything inside of the bracket.
4(s+2) becomes 4s (4*s) = 8 (4*2)
Then put this back into the equation, and this becomes;
4s+8+s-1
Then collect the like terms (these are the similar ones)
4s+s becomes 5s
8-1 becomes 7.
Therefore, the simplified equation is 5s+7

Hope this helps :)
