sqrt(x+18)=2-x

Solution

x + 18 = 2 - x

Solution

x = - 2

Solution steps

x + 18 = 2 - x

Square both sides:

x + 18 = 4 - 4 x + x^{2}

x + 18 = 4 - 4 x + x^{2}

Solve

x + 18 = 4 - 4 x + x^{2} : x = 7, x = - 2

x = 7, x = - 2

Verify Solutions:

x = 7

False

, x = - 2

True

The solution is

x = - 2
