8 x^{2} = 72

x = 3, x = - 3

Solution steps

8 x^{2} = 72

Divide both sides by

8

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^{2} - 6 x + 9 = 64

x^{2} + 7 x + 15 = 0

(x + 7)^{2} = 9

3 x^{2} + 4 x + 7 = - 1

x^{2} - \frac{1}{2} x + 1
