5 x^{2} = - 80

x = 4 i, x = - 4 i

Solution steps

5 x^{2} = - 80

Divide both sides by

5

x^{2} = - 16

For

x^{2} = f (a)

the solutions are

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

x = - 16, x = - - 16

- 16 = 4 i

- - 16 = - 4 i

x = 4 i, x = - 4 i

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

2 x^{2} - 38 = 4 x

0 = 2 x^{2} - 4 x + 3

2 x^{2} + 9 x - 18 = 0

x^{2} - 15 x + 56 = 0
