sqrt(x^2+8)-3=0

x^{2} + 8 - 3 = 0

x = 1, x = - 1

Solution steps

x^{2} + 8 - 3 = 0

Move

3

to the right side

x^{2} + 8 = 3

Square both sides:

x^{2} + 8 = 9

x^{2} + 8 = 9

Solve

x^{2} + 8 = 9 : x = 1, x = - 1

x = 1, x = - 1

Verify Solutions:

x = 1

True

, x = - 1

True

The solutions are

x = 1, x = - 1

x^{2} + 2^{2} = 6 x + 1

x = 3 x

2 z + 3 = - z

x - 1 - x = - 1

2 x 1 - x^{2} = x
