4 x^{2} - 9 x^{2} - 36 = 0

x = \frac{6}{5} i, x = - \frac{6}{5} i

Solution steps

4 x^{2} - 9 x^{2} - 36 = 0

Move

36

to the right side

4 x^{2} - 9 x^{2} = 36

Add similar elements:

4 x^{2} - 9 x^{2} = - 5 x^{2}

- 5 x^{2} = 36

Divide both sides by

- 5

x^{2} = - \frac{36}{5}

For

x^{2} = f (a)

the solutions are

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

x = - \frac{36}{5}, x = - - \frac{36}{5}

- \frac{36}{5} = \frac{6}{5} i

- - \frac{36}{5} = - \frac{6}{5} i

x = \frac{6}{5} i, x = - \frac{6}{5} i

90 = 24 t - 0.8 t^{2}

2 x^{2} + x = 28

0 = - 2 x^{2} + 3

0 = x (x - 3)

x, 2 (x^{2} + y^{2}) = (x - y)^{2} + 16
