- 3 x^{2} - 63 = 0

x = 21 i, x = - 21 i

Solution steps

- 3 x^{2} - 63 = 0

Move

63

to the right side

- 3 x^{2} = 63

Divide both sides by

- 3

x^{2} = - 21

For

x^{2} = f (a)

the solutions are

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

x = - 21, x = - - 21

- 21 = 21 i

- - 21 = - 21 i

x = 21 i, x = - 21 i

10 t^{2} + 21 t + 6 = 2 t

5 x^{2} + 35 = - 5

12 t^{2} - 30 t + 10 = 0

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

(x + 2) 2 - (x - 3) = x^{2} + 6 x - 3
