x^{2} = - 21

x = 21 i, x = - 21 i

Solution steps

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

(w) (3 w + 5) = 0

(m - 2) x^{2} - 2 m x + 2 m - 3 = 0

- 9 r^{2} - 8 r - 1 = r - r^{2} - 9

2 x^{2} + 12 x + 11 = 0

2000 x^{2} + 90 x + 1500 = 0
