sqrt(x^2-16)-2sqrt(x+4)=0

x^{2} - 16 - 2 x + 4 = 0

x = 8, x = - 4

Solution steps

x^{2} - 16 - 2 x + 4 = 0

Remove square roots

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

Solve

x^{2} - 16 = 4 x + 16 : x = 8, x = - 4

x = 8, x = - 4

Verify Solutions:

x = 8

True

, x = - 4

True

The solutions are

x = 8, x = - 4

v, v^{\frac{1}{4}} = 2

(4 x - 4)^{\frac{1}{3}} = 4

3 x + 11 x = 4

4 = 2 x + 9 + 1 - x
