x^{2} + 9 x^{2} + 8 = 0

x = \frac{2}{5} i, x = - \frac{2}{5} i

Solution steps

x^{2} + 9 x^{2} + 8 = 0

Move

8

to the right side

x^{2} + 9 x^{2} = - 8

Add similar elements:

x^{2} + 9 x^{2} = 10 x^{2}

10 x^{2} = - 8

Divide both sides by

10

x^{2} = - \frac{4}{5}

For

x^{2} = f (a)

the solutions are

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

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

- \frac{4}{5} = \frac{2}{5} i

- - \frac{4}{5} = - \frac{2}{5} i

x = \frac{2}{5} i, x = - \frac{2}{5} i

x^{2} + 1 0^{2} = 2 0^{2}

x^{2} - 10 x - 96

0 = 5 x^{2} - 7

x, x^{2} + y^{2} - 4 x + 8 = 0

x^{2} - 2 x - 12 = 0
