\frac{x ^{2} - 1}{5} = 7

x = 6, x = - 6

Solution steps

\frac{x ^{2} - 1}{5} = 7

Multiply both sides by

5

x^{2} - 1 = 35

Move

1

to the right side

x^{2} = 36

For

x^{2} = f (a)

the solutions are

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

x = 36, x = - 36

36 = 6

- 36 = - 6

x = 6, x = - 6

- \frac{3}{5} - 1

(\frac{1}{3})^{7}

x^{2} + x + 1 > 0

5 < 2 x + 7 < 13

- - 8
