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

Solution

- 2 x + 2 = 1 - x

Solution

x = 7

Solution steps

- 2 x + 2 = 1 - x

Square both sides:

4 x + 8 = 1 - 2 x + x^{2}

4 x + 8 = 1 - 2 x + x^{2}

Solve

4 x + 8 = 1 - 2 x + x^{2} : x = 7, x = - 1

x = 7, x = - 1

Verify Solutions:

x = 7

True

, x = - 1

False

The solution is

x = 7

Popular Examples

sqrt(x)+sqrt(x+8)=4

x + x + 8 = 4

10 - 4 x = 2

sqrt(5w+2)=sqrt(3w+14)

5 w + 2 = 3 w + 14

5 = 0.7 x^{0.3}

x + 3 = - 7
