b=-x-4sqrt(x)

b = - x - 4 x

x = - b + 8 + 4 - b + 4, x = - b + 8 - 4 - b + 4

Solution steps

b = - x - 4 x

Remove square roots

b^{2} + 2 b x + x^{2} = 16 x

Solve

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

x = - b + 8 + 4 - b + 4, x = - b + 8 - 4 - b + 4

Verify Solutions:

x = - b + 8 + 4 - b + 4

True

, x = - b + 8 - 4 - b + 4

True

The solutions are

x = - b + 8 + 4 - b + 4, x = - b + 8 - 4 - b + 4

(x + 28)^{\frac{1}{3}} - (x - 28)^{\frac{1}{3}} = 2

x^{2} = 3

x^{2} = 7

r, x^{2} (r^{2} - x^{2})^{0.5} = 1

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