9 x^{2} - 121 = 0

x = \frac{11}{3}, x = - \frac{11}{3}

Decimal Notation

x = 3.66666 \dots, x = - 3.66666 \dots

Solution steps

9 x^{2} - 121 = 0

Move

121

to the right side

9 x^{2} = 121

Divide both sides by

9

x^{2} = \frac{121}{9}

For

x^{2} = f (a)

the solutions are

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

x = \frac{121}{9}, x = - \frac{121}{9}

\frac{121}{9} = \frac{11}{3}

- \frac{121}{9} = - \frac{11}{3}

x = \frac{11}{3}, x = - \frac{11}{3}

x^{2} + 8 x + c = 0

4 (x - 1)^{2} = 0

- 1 = 0.95831 (t) + \frac{1}{2} (- 9.8) t^{2}

x^{2} - 17 = 8

x^{2} + 2 x + 10 = - x^{2} + x + 46
