9 x^{2} - 11 = 5

x = \frac{4}{3}, x = - \frac{4}{3}

Solution steps

9 x^{2} - 11 = 5

Move

11

to the right side

9 x^{2} = 16

Divide both sides by

9

x^{2} = \frac{16}{9}

For

x^{2} = f (a)

the solutions are

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

x = \frac{16}{9}, x = - \frac{16}{9}

\frac{16}{9} = \frac{4}{3}

- \frac{16}{9} = - \frac{4}{3}

x = \frac{4}{3}, x = - \frac{4}{3}

5 x^{2} - 6 = 14

100 = 15 t + \frac{4 t ^{2}}{2}

- x^{2} - 3 x - 1

2 (x - 3)^{2} = 50

3 + 5 x - 2 x^{2} = 0
