sqrt(2x+1)=x-7

Solution

2 x + 1 = x - 7

Solution

x = 12

Solution steps

2 x + 1 = x - 7

Square both sides:

2 x + 1 = x^{2} - 14 x + 49

2 x + 1 = x^{2} - 14 x + 49

Solve

2 x + 1 = x^{2} - 14 x + 49 : x = 12, x = 4

x = 12, x = 4

Verify Solutions:

x = 12

True

, x = 4

False

The solution is

x = 12
