x-2sqrt(x+1)=2

Solution

x - 2 x + 1 = 2

Solution

x = 8

Solution steps

x - 2 x + 1 = 2

Remove square roots

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

Solve

4 x + 4 = 4 - 4 x + x^{2} : x = 8, x = 0

x = 8, x = 0

Verify Solutions:

x = 8

True

, x = 0

False

The solution is

x = 8

Popular Examples

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

x + 4 - x - 2 = 2

2x-7x^{1/2}-30=0

2 x - 7 x^{\frac{1}{2}} - 30 = 0

1=sqrt(4-(x-3)^2)

1 = 4 - (x - 3)^{2}

x + 6 = - 9

(x/(1-x))^{0.4686}=0.537

(\frac{x}{1 - x})^{0.4686} = 0.537
