How is adding radical expressions similar to adding polynomial expressions?
You add the numbers in front of the radical signs, just as you
add the coefficients in front of the like variables
Notice the similarities:
3 cats + 2 cats = 5 cats
3x + 2x = 5x
3√2 + 2√2 = 5√2
1 dog + 6 dogs - 4 dogs = 3 dogs
x + 6x - 4x = 3x
√5 + 6√5 - 4√5 = 3√5
