sqrt(2x+15)-2=x+4

2 x + 15 - 2 = x + 4

x = - 3

Solution steps

2 x + 15 - 2 = x + 4

Remove square roots

2 x + 15 = x^{2} + 12 x + 36

Solve

2 x + 15 = x^{2} + 12 x + 36 : x = - 3, x = - 7

x = - 3, x = - 7

Verify Solutions:

x = - 3

True

, x = - 7

False

The solution is

x = - 3

x^{- \frac{1}{2}} = 0.6

0.5 x = (4 x)^{0.5}

4 = 7 - 2 x - x

u = 16

12 - 2 x = 0
