Week 4 – Addition and Subtraction of Radicals

this week in math I learned how to add and subtract radicals.

in order to add or subtract a radical the radicand and the index of the radical MUST be the same

in our equation it so happens that both our radicand which is the number 2 and our index which is also an invisible 2 are the same. if it was for a cubed root the index would have to be 3 for all of them and for the actual subtraction and addition you would just subtract and add the coefficients which in the end give us 0
