5 x^{2} = 16

x = \frac{4}{5}, x = - \frac{4}{5}

Solution steps

5 x^{2} = 16

Divide both sides by

5

x^{2} = \frac{16}{5}

For

x^{2} = f (a)

the solutions are

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

x = \frac{16}{5}, x = - \frac{16}{5}

\frac{16}{5} = \frac{4}{5}

- \frac{16}{5} = - \frac{4}{5}

x = \frac{4}{5}, x = - \frac{4}{5}

6 + 3 x^{2} = - 8 x + 2 x^{2} - 5

\frac{7}{a - 4} + \frac{2}{a}

5 (4 - 4 x)^{2} - 3 (4 - 4 x) (5 x - 1)

- 6 x + 8 = - 10 x - 20

- (- 3)^{3}
