x^{2} - 1 = 80

x = 9, x = - 9

Solution steps

x^{2} - 1 = 80

Move

1

to the right side

x^{2} = 81

For

x^{2} = f (a)

the solutions are

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

x = 81, x = - 81

81 = 9

- 81 = - 9

x = 9, x = - 9

\frac{x ^{- 3}}{x ^{- 5}}

3 t^{2} + 11 t - 14 = 0

2 (\frac{1}{4})^{- 2}

- 12 + r = 7

1.2 5^{- 0.2}
