9 x^{2} - 9 = 0

x = 1, x = - 1

Solution steps

9 x^{2} - 9 = 0

Move

9

to the right side

9 x^{2} = 9

Divide both sides by

9

x^{2} = 1

For

x^{2} = f (a)

the solutions are

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

x = 1, x = - 1

1 = 1

- 1 = - 1

x = 1, x = - 1

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

6 m^{2} n p^{2} - 15 m n^{2} p^{2} + 9 mn p^{3}

\frac{( - 3 x ^{2} y ) ^{- 2} y ^{2}}{- x ^{2} y ^{- 5}}

26 a + 13

2 + 3 x = 50
