How do I add sqrt(3x+7) to sqrt(3x-7)?

Answer 1

\[\sqrt{3x+7}+\sqrt{3x+7}\]
x + x =?

Answer 2

@keeponbleeding you there

Answer 3

The second one is 3x-7 not +7

but x+x =2x...

Answer 4

\[\sqrt{3x+7}+\sqrt{3x-7}\]
you cant add them unless you have a value for x

Answer 5

well actually the question was a function:
f(x)=sqrt(3x+7) g(x)= sqrt(3x-7)?
Find (f + g)(x).

So I thought Id add them…

Answer 6

correct just put the "+" between them and you are good to go
