9 y^{2} - 1 = 0

y = \frac{1}{3}, y = - \frac{1}{3}

Decimal Notation

y = 0.33333 \dots, y = - 0.33333 \dots

Solution steps

9 y^{2} - 1 = 0

Move

1

to the right side

9 y^{2} = 1

Divide both sides by

9

y^{2} = \frac{1}{9}

For

x^{2} = f (a)

the solutions are

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

y = \frac{1}{9}, y = - \frac{1}{9}

\frac{1}{9} = \frac{1}{3}

- \frac{1}{9} = - \frac{1}{3}

y = \frac{1}{3}, y = - \frac{1}{3}

(3 r)^{2} = 1 5^{2} - (r + (r + 1))^{2}

4 x^{2} + 3 x = - 3 x

y^{2} + 17 y + 16 = 0

x^{2} + 2 x + 50

\frac{6 ^{2}}{1 5 ^{2}} + \frac{x ^{2}}{1 0 ^{2}} = 1
