Question

squarre root of 2x+16- square root of x =4

Answer 1

did u mean:
\[\sqrt{2x+16}-\sqrt{x} = 4\]

Answer 2

yes

Answer 3

first square both sides.
so it should next look like this:
2x+16-x=4^2

Answer 4

u can't do that

Answer 5

theyr not under the same square root

Answer 6

no? is it becuase they're two different terms?

Answer 7

oh, right! duhh. basic rules!

Answer 8

okay try other method...

Answer 9

what method?

Answer 10

id multiply both sides by sqrt(2x+16)+sqrt(x)

Answer 11

to get:
2x+16-x = 4[sqrt(2x+16) + sqrt(x)]

Answer 12

x + 16 = 4(sqrt(2x+16)+sqrtx)
