- 4 x^{2} = 72

x = 2 \cdot 3 i, x = - 2 \cdot 3 i

Solution steps

- 4 x^{2} = 72

Divide both sides by

- 4

x^{2} = - 18

For

x^{2} = f (a)

the solutions are

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

x = - 18, x = - - 18

- 18 = 2 \cdot 3 i

- - 18 = - 2 \cdot 3 i

x = 2 \cdot 3 i, x = - 2 \cdot 3 i

5 x^{2} + 9 = 3 x^{2} + 27

y, 4 x^{2} - 9 y^{2} - 8 x + 18 y - 1 = 0

- 18 x^{2} - 12 = 0

x^{2} + c x + 1 = 0

t^{2} + 8 t + 19 = 0
