Answer 2

Answer:

Step-by-step explanation:

√x+1 - √x-1 = √4x-1

squaring on both

(√x+1 - √x-1)² = 4x-1

x+1 + x-1 - 2√x+1√x-1 = 4x-1

2x - 2√x+1√x-1 = 4x-1

- 2√x+1√x-1 = 4x-1-2x

-2√x+1√x-1 = 2x-1

squaring on both

4(x+1)(x-1) = (2x-1)²

4x²-4x+4x - 4 = 4x²+1-4x

4x²-4 = 4x²+1-4x

-5 = -4x

x = 5/4
