0 = x^{2} - 81

x = 9, x = - 9

Solution steps

0 = x^{2} - 81

Switch sides

x^{2} - 81 = 0

Move

81

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

- 6 - (2 x + 7) = - 2 (x + 6) - 1

5 = \frac{7}{2} (3 x + 2)

\frac{15 d ^{- 9} t ^{4}}{( 5 d ^{- 3} t ) ^{- 2}}

6 x^{2} - 23 x + 7

- 4 z^{2} - 3 z + 5 = 0
