Question

What is the solution of
sqrt(5x+1)-sqrt(x)=5
A. x=0
B. x=16 and x=0
C. X=16
D. x=16 and x=1

Answer 1

square both sides to eliminate the sqrt, then try to solve for x

Answer 2

or just by looking at the answer choices, it's obviously not 0..
nor is it 16 and 0
or 16 and 1

so just 16..

Answer 3

plug and play:)

Answer 4

\[\huge \sqrt { 5(16) + 1} - \sqrt{16} = 5\]
\[\huge 9 -4 = 5 ~~\checkmark\]

Answer 5

Yep its 16 thanks everybody
