what do you get when you add:

r+r(squared)

do u mean your adding r + r squared??

yes

well... a 1 is always infront of the variable... so just add 1R+1R^2

You can't do that.

r + r2 = r + r2.
For example,
if r = 2, then r^2 = 4 and 2+4=6
if r = 3, then r^2 = 9 and 3+9=12
if r = 4, then r^2 = 16 and 4+16=20
so r+r^2 is not 2r something or other.

To determine the sum of r and r^2, you simply add the two terms together. The expression "r + r^2" is the sum of r and the square of r.

To calculate the sum, you can follow these steps:

1. Start with the term "r".
2. Add the term "r^2" to the previous result.
3. Simplify the expression if necessary.

Let's perform the calculations:

r + r^2

Since "r" and "r^2" have different powers, we cannot combine them further. Therefore, the final result is the simplified expression "r + r^2".
