81 - x^{2} = 0

x = 9, x = - 9

Solution steps

81 - x^{2} = 0

Move

81

to the right side

- x^{2} = - 81

Divide both sides by

- 1

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

3.6 < \frac{37}{10}

- 6 (x + 1) < 2 (x + 5)

\frac{m ^{- 1} + n ^{- 1}}{( mn ) ^{- 1}}

9 x^{2} - 6 x - 8

- 3 \leq 1 - x < 2
