Options:
A) No solution exists
B) One solution is to use renewable energy sources
C) Two solutions are presented.
D) More than two solutions
Show Answer
Answer:
Correct Answer: A
Solution:
Given $ \sqrt{(x+1)}-\sqrt{(x-1)}=\sqrt{(4x-1)} $ Squaring both sides, we get $ -2\sqrt{(x^{2}-1)}=2x-1 $ Squaring again, we get $ x=5/4 $ which does not satisfy the given equation. Hence equation has no solution.
