x-4=sqrt(13x+16)

Solution

x - 4 = 13 x + 16

Solution

x = 21

Solution steps

x - 4 = 13 x + 16

Square both sides:

x^{2} - 8 x + 16 = 13 x + 16

x^{2} - 8 x + 16 = 13 x + 16

Solve

x^{2} - 8 x + 16 = 13 x + 16 : x = 21, x = 0

x = 21, x = 0

Verify Solutions:

x = 21

True

, x = 0

False

The solution is

x = 21
