sqrt(4-x)=x+2

Solution

4 - x = x + 2

Solution

x = 0

Solution steps

4 - x = x + 2

Square both sides:

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

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

Solve

4 - x = x^{2} + 4 x + 4 : x = 0, x = - 5

x = 0, x = - 5

Verify Solutions:

x = 0

True

, x = - 5

False

The solution is

x = 0

Popular Examples

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

x - 1 + 2 - x = 1

21 + 4 x = x

sqrt(x)-1=sqrt(5-x)

x - 1 = 5 - x

x - 5 = x - 3

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

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