9 a^{2} = 81

a = 3, a = - 3

Solution steps

9 a^{2} = 81

Divide both sides by

9

a^{2} = 9

For

x^{2} = f (a)

the solutions are

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

a = 9, a = - 9

9 = 3

- 9 = - 3

a = 3, a = - 3

- x^{2} - 2 x + 4 = 2 - 2 x

2 x^{2} - 4 x + 8 = 5 x^{2} + 2 x - 5

2 (x + 1)^{2} - 3 = 95

5 x^{2} - 19 x = - 12

v^{2} + 2 = 16
