sqrt(8x+49)=x+8

8 x + 49 = x + 8

x = - 3, x = - 5

Solution steps

8 x + 49 = x + 8

Square both sides:

8 x + 49 = x^{2} + 16 x + 64

8 x + 49 = x^{2} + 16 x + 64

Solve

8 x + 49 = x^{2} + 16 x + 64 : x = - 3, x = - 5

x = - 3, x = - 5

Verify Solutions:

x = - 3

True

, x = - 5

True

The solutions are

x = - 3, x = - 5

x - 3 x - 40 = 0

2 x^{2} + x + 1 - 2 x^{2} + x + 1 = 0

x^{0.5} = x

- 4 = 1 - x^{2} - 11

9 = 5 x - 4
