sqrt(x+7)+sqrt(x-1)-2sqrt(x+2)=0

x + 7 + x - 1 - 2 x + 2 = 0

x = 2

Solution steps

x + 7 + x - 1 - 2 x + 2 = 0

Remove square roots

4 x^{2} + 24 x - 28 = 4 x^{2} + 8 x + 4

Solve

4 x^{2} + 24 x - 28 = 4 x^{2} + 8 x + 4 : x = 2

x = 2

Verify Solutions:

x = 2

True

The solution is

x = 2

x - 1 + x = 1

5 = x^{0.1}

\frac{x}{160} = \frac{3}{4}

(150)^{2} + (120)^{2} = 30 41 m

x + 4 + x - 1 = 5
