(x+3)-4sqrt(x+3)-5=0

(x + 3) - 4 x + 3 - 5 = 0

x = 22

Solution steps

(x + 3) - 4 x + 3 - 5 = 0

Expand

x + 3 - 4 x + 3 - 5 : x - 4 x + 3 - 2

x - 4 x + 3 - 2 = 0

Remove square roots

16 x + 48 = x^{2} - 4 x + 4

Solve

16 x + 48 = x^{2} - 4 x + 4 : x = 22, x = - 2

x = 22, x = - 2

Verify Solutions:

x = 22

True

, x = - 2

False

The solution is

x = 22

75 x + 400 x = 16

3 x = x 64 - x^{2}

1.5 = 16.5 x^{- 1.38}
