Question

how to solve this equation radical sign n + 2 = 2

Answer 1

to get rid of radical, square both sides, so:

sqrt(n+2)^2 = 2^2

n+2 =+/- 4 (this is plus or minus 4, so there's two answers)

n=2, and n = -6

Answer 2

okayy

Answer 3

:)

Answer 4

thank you

Answer 5

How does squaring 2 on the right side give you a -4???
I realize -6 would result in a complex number not a integer 2.

Answer 6

bahaha, i did that backwards. its when you take the radical you have +/-

Answer 7

Jenny02, I would double check that solution.\[\sqrt{-6 + 2}\neq 2\]

Answer 8

good call radar :) no matter how many times i take a root or square something, i still get that backwards. radar is correct.

Answer 9

I surely understand. Working with radicals and exponents can be confusing some time. I am glad that you also agree.....it gives me more confidence lol
