sqrt(x^2-17)-8=0

x^{2} - 17 - 8 = 0

x = 9, x = - 9

Solution steps

x^{2} - 17 - 8 = 0

Move

8

to the right side

x^{2} - 17 = 8

Square both sides:

x^{2} - 17 = 64

x^{2} - 17 = 64

Solve

x^{2} - 17 = 64 : x = 9, x = - 9

x = 9, x = - 9

Verify Solutions:

x = 9

True

, x = - 9

True

The solutions are

x = 9, x = - 9

x, y = 2 x - 1

6 x - 2 x = 4

6 + (2 x - 7)^{\frac{2}{3}} = 31

x, x^{2} + 9 = 0

7 - m = 5 + m
