x^{2} - 1 = lo g_{3} (27)

x = 2, x = - 2

Solution steps

x^{2} - 1 = lo g_{3} (27)

Move

1

to the right side

x^{2} = 4

For

x^{2} = f (a)

the solutions are

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

x = 4, x = - 4

4 = 2

- 4 = - 2

x = 2, x = - 2

4 x^{2} + 18 x + 18 = 0

x^{2} + 18 x + 81 = 49

x^{2} - 1 = 6 x

3 x - 2 x^{2} - 7 = 0

d^{2} = \frac{6 \cdot 4}{31415}
