x^{2} - 8 = 1

x = 3, x = - 3

Solution steps

x^{2} - 8 = 1

Move

8

to the right side

x^{2} = 9

For

x^{2} = f (a)

the solutions are

x = f (a), - f (a)

x = 9, x = - 9

9 = 3

- 9 = - 3

x = 3, x = - 3

(x - 5)^{2} + 8 (x - 5) + 15 = 0

10 - x^{2} = - 27

x^{2} - 20 x + 51 = 0

5 x^{2} - 37 x - 24 = 0

a, b^{2} x^{2} + a^{2} y^{2} = a^{2} b^{2}
