Question

Help with adding square roots

Answer 1

\[2\sqrt{k}+\sqrt{k}-3\sqrt{k}\]

Answer 2

if you had \( \tt 2x+x-3x\) then what would you get?

Answer 3

just x right?

Answer 4

-x

Answer 5

2 + 1 - 3 = 0

Answer 6

yeah then 0

Answer 7

2x + x - 3x = 0

Answer 8

So then,

\(\tt 2\sqrt{k}+\sqrt{k}-3\sqrt{k}=0?\)

Answer 9

is that correct?

Answer 10

looks like it idk answer choices are a.) 0 b.) -sqrt k c.) sqrt 3k

Answer 11

ok, so we have agreed upon the fact that:
\(\tt 2+1-3=0\)

And same way,
\(\tt 2a+a-3a~~\longrightarrow~~2a+1a-3a=0\)

Now,
\(\tt 2\sqrt{k}+\sqrt{k}-\sqrt{k}a~~\longrightarrow~~2\sqrt{k}-1\sqrt{k}-3\sqrt{k}=?\)

Answer 12

0

Answer 13

Yes, that is the correct answer.
