9 x^{2} = 81

x = 3, x = - 3

Solution steps

9 x^{2} = 81

Divide both sides by

9

x^{2} = 9

For

x^{2} = f (a)

the solutions are

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

x = 9, x = - 9

9 = 3

- 9 = - 3

x = 3, x = - 3

\frac{3}{2} \cdot \frac{2}{2}

\frac{5 ( 7 ^{6} )}{7 ^{10} ( 5 ^{5} )}

\frac{3}{4} c d + \frac{2}{3} d - \frac{3}{5} c + \frac{7}{8} c d

(- 4 + 9 i)^{2}

4 x - 5 = - 17
