3 x^{2} + 81 = 0

x = 33 i, x = - 33 i

Solution steps

3 x^{2} + 81 = 0

Move

81

to the right side

3 x^{2} = - 81

Divide both sides by

3

x^{2} = - 27

For

x^{2} = f (a)

the solutions are

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

x = - 27, x = - - 27

- 27 = 33 i

- - 27 = - 33 i

x = 33 i, x = - 33 i

x^{2} - \frac{3}{2} x + \frac{9}{16} = 0

4 - y^{4}

12 x^{2} + 50 x + 48

x + 13 \geq 5

x^{2} + 3 x - 1341.75 = 0
