2sqrt(x+4)=2x-4

Solution

2 x + 4 = 2 x - 4

Solution

x = 5

Solution steps

2 x + 4 = 2 x - 4

Square both sides:

4 x + 16 = 4 x^{2} - 16 x + 16

4 x + 16 = 4 x^{2} - 16 x + 16

Solve

4 x + 16 = 4 x^{2} - 16 x + 16 : x = 5, x = 0

x = 5, x = 0

Verify Solutions:

x = 5

True

, x = 0

False

The solution is

x = 5
