sqrt(5+x^2)+sqrt(5-x^2)=4

5 + x^{2} + 5 - x^{2} = 4

x = 2, x = - 2

Solution steps

5 + x^{2} + 5 - x^{2} = 4

Remove square roots

4 x^{4} - 64 x^{2} + 256 = 320 - 64 x^{2}

Solve

4 x^{4} - 64 x^{2} + 256 = 320 - 64 x^{2} : x = 2, x = - 2

x = 2, x = - 2

Verify Solutions:

x = 2

True

, x = - 2

True

The solutions are

x = 2, x = - 2

x = 2 + 7 x - 6

\frac{1}{4} = \frac{1}{2 x}

6 x + 6 - 8 = - 2

x^{2} + 4 + 2 = 5 x

2 a - 5 = 3
