3 x^{2} - 15 = - 378

x = 11 i, x = - 11 i

Solution steps

3 x^{2} - 15 = - 378

Move

15

to the right side

3 x^{2} = - 363

Divide both sides by

3

x^{2} = - 121

For

x^{2} = f (a)

the solutions are

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

x = - 121, x = - - 121

- 121 = 11 i

- - 121 = - 11 i

x = 11 i, x = - 11 i

t^{2} + 4 t + 3 = 0

5 x^{2} - 85 = 40

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

9 x^{2} + 5 x + 1 = 0

(x - 2)^{2} + (x - 4)^{2} = x^{2}
