- 5 x^{2} + 10 = 30

x = 2 i, x = - 2 i

Solution steps

- 5 x^{2} + 10 = 30

Move

10

to the right side

- 5 x^{2} = 20

Divide both sides by

- 5

x^{2} = - 4

For

x^{2} = f (a)

the solutions are

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

x = - 4, x = - - 4

- 4 = 2 i

- - 4 = - 2 i

x = 2 i, x = - 2 i

3 x^{2} + 18 x + 6 = 0

4 x^{2} + 44 x + 112 = 0

- 2 x^{2} + x + 7 = 0

x^{2} + 3 x - 2 = 0, 5 x^{2} - 8 (x - 2) + 7 (x + 1) = x^{2} - 2

x, 8 x^{2} + 12 x y - 80 y^{2} = 0
