sqrt(x+5)=x-7

Solution

x + 5 = x - 7

Solution

x = 11

Solution steps

x + 5 = x - 7

Square both sides:

x + 5 = x^{2} - 14 x + 49

x + 5 = x^{2} - 14 x + 49

Solve

x + 5 = x^{2} - 14 x + 49 : x = 11, x = 4

x = 11, x = 4

Verify Solutions:

x = 11

True

, x = 4

False

The solution is

x = 11
