w^{2} = - 81

w = 9 i, w = - 9 i

Solution steps

w^{2} = - 81

For

x^{2} = f (a)

the solutions are

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

w = - 81, w = - - 81

- 81 = 9 i

- - 81 = - 9 i

w = 9 i, w = - 9 i

(2 x + 6) (x - 2) = 0

x, x^{2} - 2 x - 15 = 0

3 x^{2} - 7 x - 5 = 1 - 2 x^{2}

6 x^{2} - 5 x - 6 = 0

2 x^{2} - 18 x - 15 = 0
