x-2sqrt(x)-8=0

Solution

x - 2 x - 8 = 0

Solution

x = 16

Solution steps

x - 2 x - 8 = 0

Remove square roots

4 x = x^{2} - 16 x + 64

Solve

4 x = x^{2} - 16 x + 64 : x = 16, x = 4

x = 16, x = 4

Verify Solutions:

x = 16

True

, x = 4

False

The solution is

x = 16

x=sqrt(11-2x)+4

x = 11 - 2 x + 4

(2x-4)^{3/2}-9=503

(2 x - 4)^{\frac{3}{2}} - 9 = 503

2x+sqrt(x+4)=13

2 x + x + 4 = 13
