sqrt(6-4x-x^2)=x+4

6 - 4 x - x^{2} = x + 4

x = - 1

Solution steps

6 - 4 x - x^{2} = x + 4

Square both sides:

6 - 4 x - x^{2} = x^{2} + 8 x + 16

6 - 4 x - x^{2} = x^{2} + 8 x + 16

Solve

6 - 4 x - x^{2} = x^{2} + 8 x + 16 : x = - 5, x = - 1

x = - 5, x = - 1

Verify Solutions:

x = - 5

False

, x = - 1

True

The solution is

x = - 1

x c^{2} x^{2} - 1 = c x^{2} - x

x - 6 x - 27 = 0

5 - 2 x - 3 = 0

x, 3 x + x = 0
