x-8=-sqrt(x^2-8)

x - 8 = - x^{2} - 8

x = \frac{9}{2}

Decimal Notation

x = 4.5

Solution steps

x - 8 = - x^{2} - 8

Square both sides:

x^{2} - 16 x + 64 = x^{2} - 8

x^{2} - 16 x + 64 = x^{2} - 8

Solve

x^{2} - 16 x + 64 = x^{2} - 8 : x = \frac{9}{2}

x = \frac{9}{2}

Verify Solutions:

x = \frac{9}{2}

True

The solution is

x = \frac{9}{2}

2^{5} (x + 6)^{3} + 3 = 19

1 = 2 π \frac{x}{9.81}

x + 2 - x = 2

x + 1 - x - 2 = 1
