Question

√4+x + √4-x/ √4+x - √4-x=2 x not equal to 0,4​

Answer 1

Answer:

8

Step-by-step explanation:

fisrt of all rationalize then solve it,

(√4+x + √4-x) ×(√4+x + √4-x) / (√4+x - √4-x) × (√4+x + √4-x) = 2

(√4+x + √4-x)²/ 4+x-4+x = 2

4+x +4-x -2×√16-x² =2x

8-2√16-x² =2x

√16-x²=4-x

square both side

16-x²= 16+x²-8x

x²-8x=0

x(x-8)=0

x=0 , x=8
