25 x^{2} + 100 = 0

x = 2 i, x = - 2 i

Solution steps

25 x^{2} + 100 = 0

Move

100

to the right side

25 x^{2} = - 100

Divide both sides by

25

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} = 9 x + 4

72 y = 6 y^{2}

10 x^{2} - 9 x - 6 = 0

5 x - 3 x^{2} = 0

(x + 4) (x - 6) = - 9
